So, today while wanting to continue my Iron Crown run I was greeted with this message (IM1.png). I haven't turned on/off any DLCs nor is the save file corrupted (it still loads). So my guess is that one of the mods I use got updated and is no longer ironman compatible? How can I make sure that the save is still achievement compatible though? I don't want to waste time on 250 years of game just to get nothing.
