^ This. Or prevent the game opening a second session while one session is running?
The game hung when I Alt-tabbed out to Windows while in a loading screen a week or two ago, so I tried to close it and restarted the game. When I got to the main menu on the second session, the first session came alive again so I resumed my first game and closed the second. I'd accepted the Teir Evron God quests, but the room's reset (I got +150 exp for rediscovering it) and I cannot now interact with the altars; I guess the game is totally broken as I can no longer progress the main quest and will need to restart?
So, 2 bugs:
The game may hang if Alt-Tabbed to Windows in a loading screen.
Accessing the save folder twice at the same time will corrupt the current save.
Currently running v3.04.1165 PX1, PX2 -steam, if this makes any difference?
