If I unbox all the addon gets stuck in a loop trying to open boxes which contain unique items or contain items I can hold no more of. This isn't an issue for transmutation stones as I can disable them being looted in your settings. The item that causes me the most significant issue is the dark brotherhood box "Unmarked Sack" which always contains "Monk's Disguise" a unique item. In your recent update that changed some of the settings I have been unable to determine the category that this item fits into.
I got the item link from chat for both of these which may be helpful posted below.
