Playing with latest patch, MLB historical league.
I have found some additional detail on an issue discussed in
this main forum thread.
Playing game 1 of a doubleheader. I normally play out both games of doubleheaders with no trouble whatsoever, but this time I did something different. I had something come up, and was forced to save the game and exit during game 1 of the doubleheader. This meant that when I opened the game back up, I was in Real Time Simulation Mode, with the scoring updates at the top instead of the normal schedule bar.
As an apparent side effect of RTS Mode, I could not use the Play Menu to Start Game 2 of the doubleheader as I normally do. I could only enter game 2 by going to the League -> Scores and Schedule menu, and selecting Manage. Once I enter the game, OOTP crashes following the first pitch of the game. This has happened twice, so it was not a one-time fluke. It appears that RTS and doubleheaders do not play nicely together when one has to save the game during game 1 of the doubleheader.
