Today when I logged into the game, I found out all my progress was deleted. I didn't connect from another computer or anything, it just happened randomly. It's a probably issue with the stupid steam cloud system. When I tried to write to steam support, I could not log into my account in browser to write the complain, it says my acount does not exist (while my steam client is online...).
What can I do to get my unlocks back? I have 84% of all achievments, so it has to be obvious to anyone that I had them. Anyone experienced this?
