So I buy an Xbox for this game specifically, only to have the very first achievement stuck in "Done: Unlocking...." mode. I've tried all suggestions by Microsoft (Removing account from console, uninstalling/re-installing game, forcing a profile sync) and nothing. Not a good way to start the game, and not much faith for trying to get the other achievements. What the what? I've been xboxing since day 1 and never...NEVER had an achievement stuck like this. Can anyone here help me? It's really really frustrating. Is this game really that buggy?
