I've met the requirements for the Nice Catch achievement in Q (beat 2.38 in one move) no less than a dozen times in the last two weeks, and it will not unlock. My in-game stats show that I've beaten the level in one move. I was on XBL the first 10 or so times that I met the requirements and other achievements unlocked straight away later that day. I have tried deleting/redownloading my account, deleting my save to start over and get to that point in the game again, meeting the requirements offline and then going online, etc. Nothing has worked. It is the last achievement I need aside from playing for 100 hours, which I'm working on and gaining progress on just fine.
What can I do? I do not want to be *** out of a completion here.
