Minecraft Username: speed42jh Brief Description: Polar bear spawners are broken, the bears wont spawn and stay. Instructions: get a good polar bear setup (mine is 16 spawners) wait for polar bears to spawn How many times did you recreate this?: many times Result: Polar bears spawn then quickly despawn Expected Result: Polar bears to spawn and stay Evidence:
This is currently happening at my set up as well. One thing that may be of interest is that they despawn every 5 seconds exactly. Regardless of how many there are that have spawned, they all despawn on every 5th second on the dot.
@Speed42jh this is a known bug atm, it happens when you teleport away from your setup and come back. I've found the best way to avoid it is to just store as much stuff as you can in shulkers and only sell once all your shulkers are full
We are still investigating this, it's one hell of an doozy to track down. Feel free to mail me your spawners co-ordinates and server/world location so I can add it to my investigation.
