V2.2. -- At the end of Dragonspiral Tower, Zekrom and Reshiram cause the game to freeze (I checked the ROM with Skemple, it could be a file size issue with Reshiram)... you also made this a quicksave dungeon so unwary players will lose their items after the crash when reloading their save file.
Edit: Also, I can't get Mystery Part/Secret Slab mons to spawn, even with turning off "required item" in Skemple.
