Hello, me and my friends have a vanilla survival server on Minehut, and I've noticed that our creeper, enderman and hoglin farms only work when there is one singular person in that dimension (creeper - overworld, hoglin - nether, enderman - end). I've tested these farms in singleplayer, all work perfect. It is clear that it only works properly when you are either the only one in the dimension or the server alltogether.
Why does this happen?
