That's the workaround, the downside is it resets pitcher confidence to beginning level but it's better than starting the game over.
Another one I just found today which is probably related to mound visit freeze is player ejected game freeze. Easy fix, turn ejections off.
I like this game better that last year, hopefully they will fix manage mode for 2012 so cpu doesn't manage the game. Until then, as long as the patch the glitches which I believe they will, it's a good game.
