and another

I've used this mod in a different custom pack and have had no problems so there must be some incompatibility

Something seems to be messing up the block notify event, because having either the event itself or the world be null there makes absolutely no sense. I can just add a check to make it not crash, but if you could figure out what mod causes it (don't worry about it if you can't, I know you have a big mod list) that would be great.

it was censoredasm replacing the event https://github.com/LoliKingdom/LoliASM/blob/4.x/src/main/java/zone/rong/loliasm/common/singletonevents/mixins/blocks/NeighborNotifyEventMixin.java

I disabled it in the config and it works now

I'm going to close this since it's probably not this mod's fault. That event handler in particular does actually have a subclass that is used if the coremod is disabled for the ward focus, so that might be confusing that mod a bit.
