Thanks guys, duplicated raws were indeed causing this, as well as some other weirdness. I added a GRIFFON creature and forgot to replace the default one. I also had two item_weapon_x files with duplicated entries. Removed them and everything seems to be working as intented now.
I'm still getting something in the errorlog, but it doesn't seem very problematic.

It's something about generated instruments. I didn't mess with anything instrument-related, but I think that maybe the game is getting confused because an instrument got named "prairie". I have one entity which uses english for it's language, so that's probably the source of this.
But this doesn't seem like a major issue to me. I can just ignore it, right?
