This issue was fixed in Patch 1.49.65.
- I get the following error message: The game failed to save. Error Code: 510:a19a5568
- I get the following error message: The game failed to save. Error Code: 510:70279b77
- Going to the map resets my game progress
Unfortunately, the Lifestyle Brand is still faulty and can cause this message to appear. It occurs first after you get your earnings for the brand.
Since the game can’t be saved, all progress will also be reset if you switch to map view (and possibly if you go traveling)
Close or update the lifestyle brand and you should be able to save again. If you choose update, you will probably run into the error again sooner or later. Because of this I recommend to still not use the lifestyle brand for the meantime.
