Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Video Crashing on Level Up -- NPC issue w/Fix

I have not tried the Save Game Editor, but (until there is a fix) it looks (screenshot) like you can use LS Tools to lower Madora's experience points a little, so she doesn't level up the same time as the main character.
Make a copy of the save folder, just in case.
