Well… its probably very specific to your mod… are you editing conansandbox and is it possible you edited a level you shouldnt have? My understanding is there are camp levels to use so you dont touch the base game levels. I never touch conansandbox so I cant be sure of even where to look. It might be that you changed some engine setting too… warnings happen all the time and are often benign but seldom make a cook fail. Kinda depends in what the mod is attempting to do to know where to look.
