barycenter and I only know of one other person who has the same issue as I do. I've tried everything, from restarting my computer to verifying the game cache and even reinstalling the entire game, to no avail. Is anyone else getting this error?

Not sure if you are referring to this person. This guy has the exact same problem as you and he made a thread about it 17 hours ago.
