Microsoft has declined to accept the blame for the lack of Fez fix patch.
Phil Fish's indie studio Polytron has refused to release a new patch for its XBLA game Fez due to what it deems as exorbitant costs.
The game, released in April, features a critical bug that can corrupt save files - but the Canada studio responsible for the errors says Microsoft is charging too much for fixes to the game.
MS has responded to deny deflect responsibility back to the developer, saying that it did "offer to work with Trapdoor", Polytron's investor, on the matter of update fees, but has failed to reach an agreement.
"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," the platform holder told Kotaku.
"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," it added.
Sales figures for Fez are not public, but Polytron previously said it sold more than 100,000 copies of the game, which cost customers 800 MS points (around £7 / $11).
