Just wanted to report that I found an interesting bug. If you equip Axel or Fubuki with a D5 weapon while in the Land of Carnage and then return to Holt, you can pass another senate bill to receive duplicates of the equipped weapons. It's probably not going to be a game breaker considering the effort required to find LoC (and said effort will inevitably require obtaining stat superior rank 39 weapons), but thought it interesting to talk about anyway.
