I didn't make any roster or other changes last night. I checked my teams to see how they did in some tournaments and playoffs last night but made no changes.
The logo got reverted back to a logo that I used the first week (same with stadium stuff).
On top of that, everything this morning kept reverting again. I'd log in, see it was all weird, make changes, submit, said it was a success. Then I'd come back an hour later and everything had reverted back.
Also, all of the players stat history has been wiped out.
Things are ok now, haven't reverted since the season actually started, but I really hope this isn't a recurring problem for me.
Haven't noticed it with any other teams though, so first guess is that this is localized to me so either user error or some sort of corruption/system issue.
Thanks for responding though, I appreciate it. Just frustrated by having to do all of this multiple times this morning (and if I didn't check it this morning, could have been really bad to start the season too).
