I have been playing Wrath of the Druids now for about 45 minutes this morning when I fast traveled and the game popped up and said "Unable to save". I tried to manually save and it says
"Failed to save game progress. An error has just occurred that is stopping your game from being saved"
Then I looked at my saved games and several of them say "Data Corrupted!" as shown in the screenshot. Why is this happening, how can I fix this, and how can I prevent this from happening again?
