EDIT: So I ended up moving it to yet another location (after a fresh install) and it worked!
So the error continues. I completely wiped the install, cleaned it of all traces, installed it in a different location through steam, and copied the files over to a new place as well. The world eventually launches... Just without any of the things in the errors (which from what I can tell is literally all of the Darkness Falls POIs?
Anybody got any idea?
