Sorry for not responding sooner in the original thread,
http://www.ootpdevelopments.com/boar...ndar-year.html, but this problem has still persisted.
It is from an imported out of the park 8 game, and disabling face gen has not alleviated the issue.
This offline league of mine has never had any history of trouble in OOTP 8 except that most short season A and rookie league teams would generate only playoff schedules and no actual season. Everything else has been normal. In OOTP9, simming during the season and offseason has yielded no problems with the sole exception of crashing when advancing to January 1st.
