I am having a few problems with the new snapshot.

 I am having difficulties with glitchhub so I report it here

Serwers problem with Villagers And Monsters (1500 elements):

On version 1.15.2 I did not have such problems with the server

And a problem that is dragging on several versions, but I don't know if someone reported it. This bug is about attacking the mod. Sometimes it spontaneously changes the attacked mob to the first modification. For example from attacking the player it turns into a golden pig (my 1 mob)
