I have no idea why this particular mod is causing crashes whenever a raid starts but that's what's been happening and I can't reload the world until I take this mod out

That seems to have fixed it.

I managed to get a crash report but it mentions nothing about this mod just Architectury, which this mod uses. I tested taking out each mod that uses Architectury individually to make sure which mod it was and that it wasn't being caused directly by the API (if I hadn't gotten any results from removing individual mods I would have taken Architectury and all mods that depend on it and tested that).
