Update: In an email to GamesRadar, Ubisoft acknowledged the below report and the issue with corrupted saves in Assassin's Creed Valhalla. Ubisoft says it's "actively working on a fix" and that players can expect a patch "in the coming weeks." Until then, Ubisoft directs players to its support site (opens in new tab) for a potential temporary fix. The statement makes no mention of the issues with lost progress in Watch Dogs Legion.
Here's the statement in full: "We are aware that some players are encountering issues with their saves appearing as corrupted for Assassin's Creed Valhalla. We are actively working on fixing those. We advise players to consult the dedicated page (opens in new tab) on Ubisoft Support for a temporary solution until we can provide a patch in the coming weeks."
Original story follows...
Assassin's Creed Valhalla and Watch Dogs Legion players are reporting glitches that are corrupting save files and leading to substantial progress losses. The issue doesn't seem to be platform-specific, with reports coming from players on Xbox One, PS4, Xbox Series X, PS5, and PC.
One thread on the Ubisoft forums (opens in new tab) titled "Progress not saving" was started by someone who started playing Watch Dogs Legion on Xbox One but was experiencing frequent crashes. After switching over to Xbox Series X, callygrace says, the crashes stopped but the game would no longer save progress. Since there's no way to manually save in Watch Dogs Legion, that meant the player was subjected to playing the same mission over every time they came back. At the time of writing, the thread has 31 pages of replies sharing similar experiences. User Superman1180 says Ubisoft has acknowledged the issue.
With Assassin's Creed Valhalla, the issue seems to be with manual saves. A separate conversation on the Ubisoft forums is ongoing about players seeing "data corrupt" tags on one or more save files. "I was already level 90, I have cleared 3 whole regions. And now all my saves are gone. Completely gone!" reads one harrowing comment from user epero (opens in new tab).
For now, it sounds like autosaves are safest for the moment in Assassin's Creed Valhalla. Unfortunately for Watch Dogs Legion players, there doesn't seem to be a clear workaround just yet. Hang tight though - I've reached out to Ubisoft to see about a potential fix and will report back if I get an answer.
