You should indicate your hardware.
Villagers are having trouble searching their beds if it is 4 Y levels above them, don't put their beds too high.
You cannot tame a bat in vanilla. You're probably using a mod.
I can confirm this I recently made a similar bug report but didn't notice this until now. Using blocktopograph also shows that baby pigs don't despawn.
They do not make babies when you're watching them, they will only show hearts. I recently made an iron farm and bred 2 villagers into 10 villagers.
I looked for atleast two pigs and yes they are both small/young pigs.
I'm pretty sure this is not a bug. You will not hear rain fall if you're far from the ground. Rain has no sounds, rainfall does.
This is not a bug. Just tell your friends to update their game you don't have to downgrade
Not an issue in mine, they need to be able to reach their workstations every morning/time of their work in order to refresh their inventories. Villagers do not have to sleep to refresh their inventories, sleeping only regenerates their health AFAIK.
Up
It happens to me when the render distance is too high, lowering it should work.
Happening to me since 1.13 up to 1.14.0.3. It also happens to lava, much noticeable when you destroy a lava source in the nether.
Also happen in Villagers.
They didn't add this in bedrock unfortunately. Only Java.
