This has happened to me three times recently, right after I experienced the "4fps" bug. I'm not trying to conflate the two different things, but the cause that makes me wish to quit game is the 4 fps bug for a "restart" and I get this...
Runtime Error!
Program C:...
R6025
_pure virtual function call
At that same time, when I bring up Mechwarrior in the task manager it will still be running until I actually end task it.
If I am trying to exit mechwarrior but have not had the 4fps bug, I do NOT get this Runtime Error so far, but it may simply be chance as I am much more likely to be exiting game several times in a session from desire to restart from the 4fps bug, rather than anything else. Also, typically this is exit game from a currently connected (albeit bugged) game, as opposed to say, from Mechlab or such when I'd normally be quitting when I was simply done playing.
