I just recently start playing Borderlands 2 online with random people on Steam. I just open up my game to the public and let people play. Some of them are now on my Steam list and they join whenever I am playing.
Yesterday I started TVHM and people joined. After one mission I closed the game, and today when I started the game again I saw that the game is almost halfway done! This is quite annoying because I can not reset the TVHM, just lost lots of levels and fun times.
Is there a way for me to have it so that when I close my game nobody can go on playing?
