So I had gotten one ring equipped the first ring I found was the ring of regeneration, at least I believe it was equipped a little smaller inventory slot came out in which only the ring was placed and I couldn't switch it for anything else, I had to reload my game to a previous point and now no matter what I try I can't get the extra slot to come back. I have two rings I don't know if you can only have 1 but it would be nice to be able to put at least one on. I have tried in all Luther's forms but none work (I thought this may have been the issue but it doesn't seem like it was my issue.)

Please help if you know how to do this.

Luther wears rings in the two slots above his weapon / shield slots. No extra slots pop up or are required. He even puts amulets and gemstones there.

Ok this is what I discovered only a cutscene brings up that slot with the dog version you cans tore up to 70 items in the slot anymore will crash the game

cutscenes include The Savage Jungle Huliene temple Hive Caves
