Villagers disappearing again just like in 1.14 when there was light issues, now the problem is almost the same but a bit different so there is points what can be happening.

Because i don't have screens i will make short intro about village - So i settled into plains village who is near to outposts, maked walls around it, and gathered many villagers from other towns nearby so i have almost 30 villagers..

Now the bad thing happening

1) Almost each night i have more than 6 packs of zombies spawning inside village randomly and because i built wall to protect plains villagers from raids ( i have outpost nearby that village) and its basically looks like world war Z - zombies spawns exact on wall, and falls inside so its natural death trap to villagers. Also these zombies do not care about light level or so... they just spawn anywhere and a lot, i know its Zombie siege or something, but why Each night when someone is inside village and so many?

2)  After they killed almost half population 17 villagers left, i went to another village to gather mending village again. So there is another problem - they don't want to breed, they throws food around, making heart rain, and there pops random angry particles and no more hearts, so they wont produce kiddo... 3 hours tryed to get why, so - They somehow does not see beds.... ( i have 4 villagers inside that village and 9 houses with 20 beds) and so on, i cant reproduce population

3) Each time i log of from server i play on and after relog some time later, i have missing 1 or more random villager, just missing, no zombied or somehow killed, just , hes gone... no footprints how.. no angry mobs inside wall no nothing just.. they disappear..

4) Villager path-find when they get hurted by terrain - so this is simple, i call it suicidal villagers... last guys survived zombie siege just committed suicide. How it works? After zombie siege when others was killed last 17 was still giving water particles as sweating. I have one house who is 6 blocks high it has roof window. So what villagers did? they still was in fear, and runed trough window , they get damage, they get more afraid, and repeats same path routine till they die...

After i get some screens i will add them too
