Enable/Disable Auto-optimize

yep, and yep.  to clarify my earlier statement, it's not purely a "single category", as there's a routine that outputs both Weapons and Shields to the list.  while Optimum doesn't truly make use of this combined list, the call is still made, and the overwrite of FFs still happens.  but your combined count for those two gear categories is <= 8, so you're still good.
