A couple of months back I started a Single Player world with Minecraft 1.14.3. I love all the additions with 1.14 and was extremely excited to get into my new world.

After a couple of days I decided to start a slime farm. I looked up where slime chunks were in my world and dedicated a couple of hours on digging up to adjacent slime chunks. I didn't dig up all the hole, but at least 25 levels.

No slimes ever spawned. I tried a couple of farm designs and nothing. I stayed several nights at swamps and saw no Slime.

At first I thought it was my world, but about a week after I started a Multiplayer world with a couple of friends and one of the first things I did was dig up some slime chunks. I still got no slimes. 

When 1.14.4 roll out, we updated the world and were super excited to keep on playing. But We've had the same issue. The slime chunk we created doesn't spawn slimes and I've only seen ONE slime at a swamp. Haven't been able to find any other. 

It is a shame that this is happening. I selected Very Important priority because I think it's something extremely when playing. Not just farms but the basic spawning mechanics.

I hope this gets resolved soon. 

Thanks!
