As if the news on Cyberpunk 2077 can't get any worse, users now are reporting that their save games are getting corrupted, and word is .. once corrupt, it cannot be fixed.

While not clear as to exactly what the cause of this bug is, but it does seem to large boil down to several consistent factors regarding progression. it seems there is a common factor though, the saves that are being lost are all over 8MB in file size, 8192kb being the exact magic number that can make your play-through unreadable.

At GOG.COM it is confirmed that that Cyberpunk 2077 saved game files corrupted by growing too large cannot be fixed:

Unfortunately the save is damaged and can't be recovered. Please use an older save file to continue playing and try to keep a lower amount of items and crafting materials. If you have used the item duplication glitch, please load a save file not affected by it. The save file size limit might be increased in one of the future patches, but the corrupted files will remain that way.
