I think something is wrong with my save file in online dynasty. Can EA help?

I've encountered several glitches throughout the season, and they seem to be snowballing. I'm looking for any advice on what to do to fix the file. Here's a list of the things that have happened this season.

1. I noticed early in the season that certain stats weren't recording (Specifically, sacks, and ones in which I had user sacked the QB).
2. I had a TD that was incorrectly called out of bounds reversed to a score, and despite the change, the stat didn't record for either player (Though I didn't pay attention to the score/if it was affected, as the game was comfortably in hand)
3. During one week in which I had a visitor scheduled, for some reason it just disappeared, and the visit didn't happen. This most likely cost me a huge recruit, as there was a multiplier bonus based on complementary positions.
4. I had a game just drop in the middle of a game (Right before the final whistle, basically, as I was in the last minute of a big win), and it said that I lost internet connection (I don't know if this was actually real or not, as internet seemingly was working on all of my other devices).
5. I had a game in the college football playoff where again, my player had a touchdown called incomplete, and in this case, while the call was overturned, not only did the stats not show, the score never counted in the menu (Though in-game, it showed the correct total--at least as far as I recall, as I didn't pay total attention to it after I initially noticed it). I played a really bad game, and the CPU took it to OT (It was 28-28)--except when the final whistle sounded on regulation, the opposing team started celebrating, and the announcers acted like the game was over. I tried to advance past the cut scenes, and the menu, but it showed the final as a 28-21 loss for me. I asked the commissioner of my league, and jumped out of the game just in case it would report that result, incorrectly, and it didn't appear to, as I confirmed immediately thereafter that I could re-load the game/that it would let me play again. The commissioner reset the file for me just in case.
6. When I reloaded the game, I won again (This time 36-35--a real barn-burner, as I came back from down 28-0 to score the winner with 0:14 left), and this time when I went back to the menu, I clicked ready to advance. The screen showed the file advancing, and when it reached the normal screen to show that it had advanced, it didn't update recruiting (And in fact, there was no R1/L1 control/options on top of the screen, nor an X at the bottom to advance past/back into the dynasty file), and it seemed to apply 0 points to my coaching progress, even though I had just won a playoff game (Though, this pane re: not seeing anything in terms of coaching points being updated is not uncommon in my experience, as I'm in another two-team dynasty in which, when you're the party that advances, it leaves you on this pane with no ability to see your commitments or coaching progress points updating). Usually, I just back out of the game, either by going back to the menu or closing the game completely so that I can reload it to view my commitments/get a screenshot of the confetti screen accompanying their commitment). In this case though, I had no choice--I had to back out by shutting down the game, as no screen inputs were available or working. However, when I reloaded the dynasty, I'm right back where I was before the advance, with no game showing as being played on my end. This doesn't make any sense.
7. I started noticing that my #1 wide receiver was snapping at defensive back about midway in the 3rd quarter (Something that I'm sure when it began, but I'd bet contributed to the 28-0 scoreline, as guys were just getting open with abandon, and I checked instant replay). This was especially weird because I could find him nowhere on the depth chart at corner (Nor SCB), or safety, and I had to reorder the depth charts to get this to clear. However, I also discovered it once during practice, and despite trying to reorder the depth chart, on that occasion, I could not get it to clear without exiting out of practice. Furthermore, it's weird that the game allowed two #0s onto the field at the same time on defense (Though I don't pretend to know what tolerances it has for that, or if it will just glitch/not notice and allow this to go on).

Any help with these issues would be greatly appreciated. I love being in this dynasty with this group of guys, but these issues/the possibility that the file is somehow corrupted is a major drain. It takes it from being a fun experience to a time-sink when I have to replay games for the second, or maybe third time now, and then have to do internet research about what went wrong--and I have a move overseas coming up that could further limit my time in this dynasty. Thanks for your help.
