hey guys, relating to the OP, I'm the owner of the team. Just wanted to thank RyanCane, Marbro, AC, and Wise for their help and/or offers to help.
I ran through this with builderbob last night and, for the regular season games, the correct gameplan was being called, but not the right play selection. We went through the AI and found the hole, so it's all fixed.
For the beginning of the season scrimmages, it was definitely calling a different AI, so the logical suggestion was the one you guys had posted - that the default scrimmage AI was set to something other than "no preset". But nope - when I went to that page, everything was "no preset". I'll run a scrimmage in the next couple of days to see if it's still happening. if it's all set, then we'll chalk it up to a user error of soem kind. If it's still running the basic AI instead of our "active" AI, then maybe there's a bug where the team used to have something in the default Scrimmage AI and when the team changed hands, the value in the database still holds that value but the screen says "no preset". Or something.
Regardless, just wanted to thank you guys for your help and responses.
