It's a problem exacerbated by the overflow of various kinds of consumables, food items, and notes/books. I could happily have consumables halved or more, food items gone directly to camp storage, and all things written stashed in a miniature giant pocket-bookshelf. I have a bad habit of never using consumables though, so it quickly stacks up to frankly ridiculous proportions. I'm at the end of act 1 and I have enough consumables to start a wizards schoold and equip an army.
