Description of the issue:

for some reason players get disconnected when walking on top a conveyor belt and they cant join until the get moved away from it (have to edit nbt data). i dont know if its relevant but it was in a 2 block high tunnel.
i have on the Server Performant. but i removed it and the issue is still existing.
