Make sure you send lineup changes to PA now. He's handling everything- we made the switch now after my OOTP went bankrupt (or something). After I did contracts and simmed yesterday, my game froze while uploading. I rebooted, and all systems were a-****ed up. The initial problem was that all the contracts I had put in tuesday morning had not saved. That wasn't so much an issue, but everyone's lineups were a mess... well, they weren't at all. It had reset everything. There were more problems I discovered, so I just stopped to avoid screwing up the league completely.
So this was just a clarification, as to why the sudden change instead of waiting till the next season. I'm not leaving the league, though, I've decided to stay and enjoy PA's league.
