This error window popped up immediately upon loading. It seems very similar to a couple of others on the forum but not exact so figured I’d start another thread. No steps to replicate, I only loaded the game from a save file. Two errors occured, I’ll post both and my log file

Keep posting these, because I need to fix the source location for each one even though the lower level assertion is the same.

Thanks guys!
