My problem probably has the same cause, so that's why I'll revive this thread.
I gave the AI one job... one... and now I've got 2 minor league teams with 45 players, another one with 5, and my AAA team has 0. One of the 45 player teams has 36 pitchers. I've got to sort through all that flotsam and distribute everyone around my 8 minor league teams again.
God only knows who's been released. Or signed. I don't have the heart to look yet. I'm considering just binning the league because I hate the idea of spending a few hours cleaning this up.
Somehow, my empty AAA team is 7-5 and I do not have ghost players turned on. I wish I had the 'save box scores' settings on for that league but this is another topic...
The worst part is that I didn't even give control of promoting/demoting minor leaguers to the AI. I just wanted the AI to sign some players to top off my lower league teams, so I handed over sign/release minor league players to my minor league managers.
...and why can't the assistant GM do that? It's the only reason I hired him.
"
I don't need to create a copy of this league beforehand", I thought. "
I've got roster limits turned off. The AI can't promote/demote anyone because I'm in charge of that. This feature has been around for a long time. What's the worst that can happen?"
Ugh. It took years for me to finally trust the AI enough to work with my minor leagues. This was the first time I had done so. I've been playing OOTP for something like 15 years, and I'll likely play it for 15 more. But I'm never letting the AI near my rosters again.
