In my game, Dorn starts off with his Plate Armor and Two-Handed Sword, however if you unequip these items, he cannot put them back on. The items have a red border around them in his inventory. He cannot wear armor that is above studded leather. He also seemingly cannot use any two-handed swords. What is the problem? He doesn't have anything draining his stats or anything like that, so I don't know what it is.
