FromSoftware recently sent out a Tweet acknowledging the issue. A translation of the Tweet reveals that the studio is aware of a bug that causes data to not be saved properly under certain circumstances. While the issue is being sorted, the studio advises you to close the game before putting your PC to sleep.
FromSoftware is investigating the issue
This isn’t the first time FromSoftware has struggled with save file issues. WhenElden Ringlaunched in 2022,some players experienced save issues on PS5 and PC, though the studio did release a fix.Elden Ringunfortunately had other issues on PCthat affected performance, and they also needed to be addressed by patches.
Some Reddit users on the Armored Core subreddithave complained about the game not properly saving their progress, suggesting the problem isn’t exceptionally rare. The problem is worsened by the fact thatAC6doesn’t have multiple save slots, leaving you reliant on one precious save file. This makes it even more important to follow FromSoftware’s advice until the bug is patched out.
