Hi! I foun this crash when playing your mod with OP trophies, it seems Golem Dandore isn't checking that the owner assigned to the snow golem isn't null before saving it. Here is the crash report.

I'll look into it, thanks

it turns out it was actually the loading that had issues rather than the saving, but hopefully this has been fixed by some changes i made to null check during entity loading
