The latest patch for Fallout: New Vegas is reportedly causing some Xbox 360 users serious problems.
"Great, get the day off, settled down in front of the Xbox to play New Vegas and guess what, it freezes. Thanks Bethesda!" wrote one poster.
"As with everyone else, the new update has wrecked my game, got the warning about losing content and now it won't load up my past saves."
A post on publisher Bethesda's Twitter feed acknowledged the problem and insisted a fix was in the works.
"We're aware some folks are having New Vegas save issues," it read. "We're working with Microsoft on this and should have more information soon."
This isn't the game's first bug-related controversy the action RPG sequel has been plagued by technical issues since launch.
Reports on Tuesday stated that a number of senior staff at developer Obsidian have been made redundant this week.
