 Description   

I capture zombie villagers in my underground base and put them in a holding pen. I cure them then put them in my 'village'. They sometimes last for several minecraft days before disappearing. Sometimes they disappear if I turn my back while they are in the healing phase.

I think we, and others, have done a fair job of eliminating the variables. It does seem like sometimes a villager just disappears; I just can't account for the ones I'm losing occasionally at my spawner thing. I'm totally out of ideas except that idea of sticking quite a lot of them in the ground (array of 1x2 or 1x3 holes) with trapdoors on top. And perhaps having an upside-down half-slab for the floor beneath them so there is nowhere at all for hostile or other mobs to spawn. If we do that test and one disappears, then we will know for sure it's not our fault, yes?! I guess I'll have to try it. If I get results you'll be the first to hear about it

It was a cured villager. Nope the whole place is well lit and completely fenced in to prevent spawns inside the fence. The only disappearance I have noticed was when I slept in the village I was building right after I had cured a second one. Both were villagers, one blacksmith and one librarian. They both ran into lit "homes" as night began. I entered a building an used bed. Left bed and could only find the Librarian.

Because of this I have refused to use the bed I have in the village for worry that the issue would repeat. It leads to very interesting nights. Since then I have cured several other villagers and none have vanished mysteriously.

Nah, Andrew has the apple/potion thing going all right. How about inside the homes, are they lit up too? Zombies can be pretty sneaky - lighting the place up only reduces the chance of spawing; it doesn't rule it out. I hear in certain circumstances they can wander off and get lost (hence the fencing in) but you have a fence and so do I. Is there any environmental hazard a villager might fall prey to, like lava or drowning? How about cacti? One of my Iron Golems died by trying to get through a cactus and I actually observed that. They're none too bright. My village seems not to be losing any (probably because I spend so little time there as would attract mobs) but with my Zombie Villager Rehabilitation Facility (if you want to see it - https://www.youtube.com/watch?v=thPB8Ny-MGI) I'm not so sure. I have made absolutely certain (?!) zombies can't spawn where the cured villagers are housed; I have a glass ceiling that comes down leaving only one block space between it and the floor (the villagers don't suffocate) which has torches on every free block, so that in theory no Zombies should be able to spawn inside according to the basic spawning rules as per Minecraft Wiki. I've also tested to see that other mobs (little slimes or spiders) that might spawn elsewhere and then slip in aren't interested in attacking them. But since you wrote I've been watching carefully and I too am finding that once in a while there is an empty minecart where a villager should be. Makes me think that the occasional villager will just disappear because of a bug of some kind. Last idea I have: maybe if there aren't enough villagers (more than just two) they might tend to despawn. The ultimate test would be to chuck them down a 1x2 hole with a trapdoor and see what happens to them then.

It should turn into a villager... that's a tough one. Are you sure you fed him the apple or threw the potion at him?

Comment by Andrew Hemond [ 03/Aug/13 ]

I don't think anything got him. I saw both villagers before I used the bed. I had done a count, checked to see they were both inside houses before I used the bed. Two villagers. Slept. One villager.

I had something similar. I happened to be building a sort of way station in a village to connect up some railroad. I wasn't paying attention. Because I was there, mobs were spawning. I looked up one day and there were no villagers left, all dead, killed by zombies while I was stuffing about. My presence had brought ill fortune to that village and now my village was deserted. I am fairly sure what happened was that because you were there a zombie spawned while you weren't watching and killed that first villager. Light the thing up like a fairground, was my solution - in addition to fencing of course. After almost two full days spent transporting in new villagers from elsewhere. Don't forget any rooftops and such. Also, I put about five Iron Golems there. Since then, all present and correct.

I built a village that is completely fenced in. I cured one zombie villager and watched him wander around and into homes. Then a couple nights later I cured another. I decided to use the bed I had put in one of the buildings when I had been skipping nights to get the fence up safely. Next day only the second villager is there. The first has despawned.

Hi Adam,
I feel pretty confident in confirming both parts; it looks like that's all been ironed out. I spent many months building a zombie villager thing and in all that time I didn't once have zombie villagers de-spawning either before or during curing even when sometimes I forgot what I was doing and left the scene; they were still there when I returned. After curing I am losing the occasional villager but that's really rare and I think it's because my 100% mobproof villager corral design is not 100% mobproof. I package them up and transport them in Minecarts in which they stay permanently; I suppose that could be a variable?!

Up there I've posted a screenshot of the finished Zombie Rehabilitation Centre! - and here is the link to the YouTube: https://www.youtube.com/watch?v=thPB8Ny-MGI

Comment by Adam Stanley [ 13/Jun/13 ]

Im not sure if this links to MC-1980, as that is during curing, and this is after curing.

Can someone confirm that both stages have been fixed so that the don't despawn a few minutes after they have been cured?

Screenshots: first the hotel, and then the spawner set-up. This is the first working version, plan is to railroad them straight from the curing pen all the way to the hotel - I wonder if they will despawn in transit?!

Comment by Nathan Hall [ 05/Feb/13 ]

Hello Claire,
I think it can't be the eggs; a Zombie Villager is a Zombie Villager and you'd expect the game to treat them all the same regardless of how they came into being - if not then that's a bug in my view. I've attached some screenshots (or tried to anyway rrr). First the 'hotel' where I seem to be having no problems keeping my flock - but then I'm not sure as I was sure I had five and then I got another and still had five; but that's not much help. I built the hotel from this YouTube - http://www.youtube.com/watch?v=kZo5dBHnI0w&feature=related - do you think if I put the extra storeys on it my Villagers will start mating? That was the plan or the hope anyway. With the hotel I've stopped them going to the upper levels as I'm fairly sure I lost the first ones by suicide - jumpers. They just kept going up - like they should - and stepping off - like they should - except they don't mate so they do it again and again until they've lost all their hearts (is my theory, I was upstairs at the time). I've got a double high fence around it so if a Zombie does spawn in my imperfectly lit lair they won't be able to reach the Villagers over the fence. I put quite a few Iron Golems in there as they are not reliable.

Zombie Villagers are definitely aggressive during the healing process, as I discovered by standing at the fence taunting them. That's how I got the idea to bop them once in a while to 'reset' them (not to provoke them) and let them have a go at me too. I don't know if it works. I tend to think that if I'm losing them from the hotel they're not despawning and I'm just not seeing some hazard or it has to be a bug. If you have a Villager properly penned and protected, regardless of where he came from he should be permanent and if not then that's a bug in my view - or a change needed to the way this mob behaves.

Other shot is the new spawner with Extractomatic technology. Plan is to railroad the cured Zombie Villagers straight from the curing pen to the hotel and dump them automatically, as now I'm getting about as much as I can handle. I've not had any despawning problems from this and I'd expect less than with the hotel as the process is as fast as I could make it whereas before I had to lead the prospective Villager quite a merry dance from the spawning area to the hotel, after dealing with any mobs that spawned with him. Best I have to offer is making the process quick, to minimise what must be a randomly determined possibility of despawning. Could be that some mobs are destined to despawn early and there are no special rules for Zombie Villagers.

Hi Nathan,

Those are interestng points and tips, thanks for sharing!
To clear up the confusion on my 'spawn eggs' comment, I went creative to use the spawn eggs after I realised my cured-villagers were vanishing to see if it was just them or villagers in general. Testing purposes there.

The zombie villagers I had cured were a mix of zombie-spawner created and just plain natural spawned on the surface at night time. I have a little sealed-off 'house' near the zombie spawner where I put cured villagers in that came out of the spawner and I also had a big underground village up nearer the surface where I'd lead cured-villagers to that were just spawned at night time by the game. It was when I noticed those surface ones vanishing that I noticed the ones in the house near the zombie-spawner also vanished. There's a few golems in with the big village when I was trying to figure out what was going on.

Before I moved the 'surface spawned' ones in to the big underground village they were in a little house near my home and they actually stayed there for days before they mysteriously vanished, that's when I began noticing something was a little odd with the cured zombies and started paying more attention and trying out little tests.

I will certainly try messing with them during change and I'll see how that works out and comment saying how it goes. Though no zombie villager that is going through the curing process has ever been aggressive towards me, though I have not struck them or anything to provoke them.

Hello Claire,
I now have a zombie spawner which I am working on both in Creative and Survival (using same seed). Am PC player. In Creative, when I extract the Zombie Villager, I do the potion and golden apple thing and he turns into a Villager and stays that way, just as in Survival. I have noticed that not all the potions work, for example the harming potion doesn't seem to work in Creative. In both Survival and Creative, Zombie Villager are mobs until they are cured before which there is a chance they will despawn. As soon as I have a Zombie Villager in the holding pen I drop everything and get him potioned and appled as fast as possible. Then - and I don't know if this helps or not - I 'interact' with him. I stand near the fence so he can wop me one occasionally, and I sometimes strike him about the legs with a fish or a torch, something that won't hurt him much. I don't think I've seen a mob despawn while you are actually engaged in combat with it. I'm not having any trouble with mobs despawning in the healing process unless I leave them, lose sight of them, or do not act fast enough, either in Creative or Survival. I suspect the monster egg. But but - do you mean spawn eggs such as you get in Creative mode? Because if you are in Creative, aren't golden apples and splash potions limitless? Signed, confused. Maybe it has to be a naturally spawned Zombie Villager, either from a spawner or thin air. My advice is to work fast with the rehabilitation and keep them angry by prodding them until the change. Make sure mobs can't spawn in the Villagers' pen, as if a Zombie spawns that can mean reinfection and despawning, or death. I put Iron Golems in there to keep them safe. With this spawner system of mine - bit of a bonus - if what he's selling is no use to me I can just shunt him back in the hole and he gets re-infected by the next Zombie, until I'm happy with the number of pieces of paper he wants for an emerald

Comment by Defaeco [ 05/Feb/13 ]

This is the exact scenario I am trying to do. I have an underground village and if I spawn villagers with a monster egg, they stay there just fine. If I cure a zombie villager and put it there, they eventually vanish. I feel they're being treated by the game like hostile mobs rather than an ordinary villager. Such a waste of golden apples and splash potions
