Bug: Storage stacking changes durability
Adding identical weapons of different conditions/durability to the storage changes the condition of the newly added weapons to the condition of the weapon(s) already in storage. As long as a weapon is not broken, you can then artificially improve the condition of all low durability weapons in your inventory, if you have at least one identical weapon with perfect condition. Works the opposite way too, which is how I noticed. Added new bows to storage but it had a poor one and all bows were set to liw condition. Haven't checked if the exact same thing happens with food.
