I killed Mog and took his key (And all his shiny weapons his minions had.) but then I had to go for dinner, so I saved and quit the game, after dinner I went back on and went to the safehouse, and now it won't open up. It says item required even though its in my inventory...or those that only open the chest and not the safehouse...it those say treasure key 0.0'
Are you sure you're at Mog's safehouse and not at, say, Sleth's safehouse?
