Pretty sure this is a bug. Apologies if this has been posted before as I stopped looking back about 10 pages from the bottom of the thread. Issue outlined in these two threads:
http://www.ootpdevelopments.com/boar...pearances.html
http://www.ootpdevelopments.com/boar...rly-1900s.html
I believe these are both the same issue. Using 13.2.6 on Windows. Not sure why this is happening. It definitely should not be happening in pre-'30s leagues. In my testing from the second thread linked, it only seems to be an issue when the Pitcher Stamina in the Strategy setting is anything below Very High. Disregard the schedule comments in that thread...doesn't seem to play into it after all.
