Golden Room Glitch
I'm wondering if this has happened to anyone else. I managed to get all the gold bars, got the exclamation mark on the map but the room refused to open. I tried save/reload, turn XBOX off etc but nothing seemed to trigger the room to open. I continued on and finished off the game and got my 100% completion acheevo.
I then started a new game and the damn room still won't open. It's not even showing the exclamation mark on the map anymore either. My level has remained etc but it seems like the game never registered my gold bars collected or something. Pretty annoying.
