Recently, it became known that a game-breaking bug caused by a defective patch was affecting the playthroughs for less than 1 per cent of players who had purchased Fez. Developer Polytron, who had released the game exclusively for XLBA, explained on their official website that unfortunately, because it would cost so much to re-certify the game and resolve the problem, they would not be going ahead with putting out a fix.
In response to this, Microsoft sent a statement over to Kotaku. It reads,
"Polytron and their investor, Trapdoor, made the decision not to work on an additional title update for Fez. Microsoft Studios chose to support this decision based on the belief that Polytron/Trapdoor were in the best position to determine what the acceptable quality level is for their game. While we do not disclose the cost of Title Updates, we did offer to work with Trapdoor to make sure that wasn't a blocking issue. We remain huge fans of Fez."
