I have a real good design for an endermen farm. It works perfectly fine on my singleplayer(1.16.2) world. I now have an exact copy on a SMP Paper 1.16.2 server, and the endermen are not agro-ing at the endermite for some reason.
Enderrmite is in minecart, in both cases (single player and server)
Endermite is about 4 blocks up from the ground (located on the 6th block region, in both cases)
Is there any way I can solve this? I can contact the server admin.
