So for everyone that get's the int32 error, do the following:
1. Connect to your game
2. Open the menu and start counting the slots that are full until you reach clothing
3. In the Durability manager, go to the slot that is your first clothing item (e.g. 7 weapons, 2 bows, only Wooden arrows, 2 shields -> 1st clothing slot is 13)
4. Set each slot that actually holds clothing to 0 (e.g. normal clothes plus winter thingy you get from the old geezer -> 13-15 needs to be set to 0)
5. Save and reload
6. Click Load current values
7. Profit
@GamePil maybe you could also add this to the first post if it's confirmed working (for me it is, don't know about US releases though).
