Over a minecraft 2 days in game all 32 villagers have despawned/disappeared. Prior to this it was happening along with doors despawning, minecarts despawning and friendly mobs in enclosures like cows and sheep. It isnt just one or two now but whole herds and every door and all my villagers in a secure trading hall.

Not sure if I need to do seperate bugs. 

So my other bug is that my game just quits out about every 30 minutes. There is a big gap when I reload it between saves. Its very very annoying when you are constantly having to repeat things that have taken effort to do in survival.

Im not sure about the version Im playing just that its the Nintendo switch minecraft and its upto date. I thought it was version 1.12 but nit listed.
