My friend and I decided to play Gems of War. He started his account on my computer and played for a bit. He then went over to his computer and installed the game and resumed playing. I went on my computer (where he was previously playing) and signed into my Steam and attempted to play the game. When the game loaded in it pulled his save information. We have tried multiple solutions such as uninstalling and restarting Steam.
I just want to be able to play the game without his information in my Steam account. I should also note that I do not have an account yet because it keeps signing my friends account in under my steam and his.
I have no idea how this is happening or why. Any help would be appreciated.
