"First of all, go to
C:\Users\*YourUsername*\Documents\WB Games\Batman Arkham Knight
and back up that whole folder. Do the same with
C:\*YourSteamDirectory*\Steam\steamapps\common\Batman Arkham Knight\BMGame\SaveData
Then go into C:\Users\*YourUsername*\Documents\WB Games\Batman Arkham Knight\76561198040228519\SaveData\backup
(The numbers may be different, but there is only one folder there anyway). Pick a recent file (I picked one from ten minutes before the glitch),delete every symbol in file's name after sgd and copy it. Go to
C:\*YourSteamDirectory\Steam\userdata\79962791\208650\remote
(the numbers may again be different. If they are, search for any files containing 'bak' in the userdata folder.) Then paste that backed up file in there and move the other 2 files into your backup folder. This is what worked for me anyway. Good luck!"
