I have recently discovered a glitch that might be useful if your cart is full. It allows you to go over your maximum encumbrance. first you have to have access to a cart so you can't use this in a duengeon unforteuntly. find a tresure pile when you still have access to your cart or make your own by dropping something on the ground. now once the tresure pile is open switch to your cart now you can put everything inside your cart into your inventroy allowing you to go over your maximum encumbrance but you can't pick up anything else though. I found it while I was dropping treasure piles on my ship.

I had something similar happen that was letting me go way over my limit while I robbed stores. I didn't find the mechanism, though. I just saw I was still picking up loads of stuff off shelves when I should have been full long before.

I have recently uncovered another helpful glitch. If you want to recover spell points and you have a magical item that casts a spell set the spell to ready to be cast then abort the spell the magic will go to your character.
