Watch Dogs Legion players are reporting a save-corruption bug that the game is currently suffering from, which can lead to an infinite load screen.
Reports of the game corrupting save files have emerged on reddit and the official support forums. According to these reports, Watch Dogs Legion suffers from a major bug that could lead to corrupting the save files of the game. It can occur on PC when the player tries to quit to the main menu. During certain circumstances, after quitting to the menu, the game can freeze for a longer period of time during which if the player chooses to force quit the game, it can lead to the save file getting corrupt.
There are also reports of players playing the game for hours only to end up with a corrupt save. This could lead to the player loading one of their previous save files only to booting into an infinite load screen.
One of the theories is that this is due to the multi-threaded save nature of the game on PC. There are multiple saves being made at a time, and when one of the save files is being written by the game, it can be disrupted midway leading to the corruption of the save file itself. There are multiple threads of the save data being written on PC which get overlapped leading to the issue with the save file on PC.
As far as we can tell, this problem is mainly reportedly on PC and we haven’t seen any reports of this issue occurring for PS4 and Xbox One. If you are one of the users who is affected, you have to wait for a patch by Ubisoft. Just to be on the safe side, always make a backup of your save file on PC.
