I ran into an unfortunate bug, as the title says Edér lost all of his equipment after I swapped him for Maneha in WM1. I completed WM1 and went back to my Stronghold and now the very good equipment including his inventory, quick slots equipped items have all disappeared. Very irritating. I have many saves along the way but no saves before I swapped Edér and Maneha... It seems that he instantly lost all his items after he left the part.
Is there a solution for this?
