Me and my little brother use the same computer for our seperate Steam accounts, so today I looked at his library and instead of saying 'PURCHASE' like it normally does, it says 'PLAY. This came as a surprise, and got my brother to log into his account to see if he got it too. We clicked on PLAY on Skyrim (using my game on his account) and it said that we should share our games seeing as both our accounts are always logged in at different times. He wanted to play Skyrim for a long time so I clicked okay and got an email from his account asking for authenication. I clicked it so when we went to his account, it said 'shared with ma573r_sw0rd' which I was aware of. We launched the game, however it said at the bottom of the launcher, that some mods may have been unsubscribed or something like that. We launched the actual game, and it came up with my save files from the last time I played like usual. So basically, all I'm asking is if he plays the game on his account, will it affect my save files and mods? Also has this happened to anyone else? Sorry for the long post.
