A new Rainbow Six Siege patch is reportedly corrupting players’ hard drives, with the PS4 version of the game currently experiencing a ton of issues.

The new patch was distributed to the PS4, Xbox One and PC versions of the game, though only Sony’s console appears to have been affected by this problem. According to players, downloading the patch has caused their PS4 friends list to crash every time they attempt to access it, while others have reported that it has corrupted their save data altogether.

Ubisoft has told players not to use the party feature on PS4 until the issue is resolved, though there has been no timeframe given as to when players should expect a fix. While the crashing issue is concerning in and of itself, the patch potentially bricking PS4 owners’ HDDs is a far more pressing problem, though there appears to be some confusion as to what is causing the trouble.

While many players are reporting that the new Rainbow Six Siege patch has caused their hard drive issues, Community Developer Craig Robinson tweeted: “It looks like it is a firmware update issue. Not tied to Rainbow.”

However, Community Manager Matt Shotcha has confirmed that the team at Ubisoft are looking into these claims, suggesting that they could be linked to the game after all. “If you feel your console may have been “bricked” please reach out to me as soon as possible,” he posted on Reddit. “We would like to try some troubleshooting and see if we can get you back up and running again.”

Shotcha also noted that Ubisoft is working with Sony in order to “determine the root cause of the issue,” though no further information has been provided at the time of this writing. Ubisoft’s official statement regarding the PS4 crashes reads: “Players have reported a crashing issue regarding the party invitation. We are cooperating with Sony on this issue and would advise you to not use this feature until a resolution is found.”

Though there’s no confirmation of whether or not the patch really is bricking PS4 HDDs, with many players reporting the problem and the patch already leading to its own set of issues, it’s advisable that Rainbow Six Siege players hold off on making the update until Ubisoft and Sony give the all clear.
