I lost complete folder Program Data and Roaming folder. Inside are saved files for Dead Island Definitive Edition Challenges and Achievements. That mean if I reinstall Windows I lost everything.
In Dead Island Definitive Collection it's not possible to delete Challenges and Personal Statistic even if you Delete your Progress with character and start from beginning. Personal Statistic stay. Except if you enter in User Name Roaming Steam and inside are numbers for Dead Island and Definitive Edition, on that way only you could delete Personal Statistic. I don't know where my game save now because all folders are lost. Under User I have only my name and Public, if I click on my name App folder is lost as well.
This Microsoft is Cesspit full of pigs.
I can't believe, look what these MS idiots done.... I'm not sure even I would be able to back that...
