Downloadable puzzle-platformer Fez's patch released today may corrupt saved games, according to developer Polytron's Twitter post and website. The posts advise against downloading the patch unless players already cannot access the game.

Generally you don't want to see "DO NOT DOWNLOAD" in patch notes.

"We're floored that this wasn't found in testing," the website states. The title update was intended to correct several bugs and performance issues that have plagued the game since its launch.

If the patch has already been downloaded, the site advises affected players to delete their system caches as a potential solution. If this does not protect their progress, no other workaround is known.

[UPDATE] Following the publication of this story, Polytron posted an update to its website stating Microsoft had pulled the patch from Xbox Live.

"Microsoft has pulled the patch out of LIVE for now, so at least the problem won–t affect new users," reads a line from the statement. "We're trying to find out what happened and fix it as soon as possible. Like, in less than two months. YAY GAME DEVELOPMENT!
