If the modifier maximizer attempts to equip an item that is already equipped in another slot, it will acquire the item, which is fulfilled by unequipping it from the other slot. For example, a common case is that I maximize myst with no saucepanics in inventory but 2+ in my closet. The maximizer will uncloset one saucepanic, equip it in mainhand, then unequip it to be put in the offhand, and then fail because equipping an offhand weapon without a mainhand weapon is an error.
To fix this, the maximizer would have to acquire equipment in a way that is not satisfied by unequipping, or pre-acquire multiple copies of equipment that is to be used in multiple slots.
