I found the bug. It is because I adding the move through village AI task to the entities in the nether and that causes chunks to load. I will mark it as solved. DO NOT ADD MOVE THROUGH VILLAGE AI TASK TO NETHER ENTITIES.

but I am just getting warnings and I do not where to set breakpoints but I tried setting breakpoints all over my code but nothing is related to my mob because my mob is extremely basic and I am not that expert with this call stack stuff

I am making an entity and it is almost an identical copy of a zombie that spawns in the nether (hell) and I am getting cascading World gen error when exploring in creative in the nether, even though I am adding over 10 entities in the overworld without any troubles. I tried un-registering the entity and the problem went away. I am not adding any extra mob gen and I do not even know how to add biomes or dimensions so I do not even know why this happens.
