Hello everyone

I've been playing a lot lately, and I've always had problems with the game freezing in the middle of tracks or in the loading screen, but that's never been a major issue for me, since you just have to restart the game. no big deal.

Yesterday I beat my records on a few tournaments and went from 561 to 567 medals, then stopped playing for a few hours.
When I launched the game the next time, all the medals I had won had disappeared, and I was back to 561 medals.
My scores were saved on the leaderboards though, thank god...

So, after a bit of googling, some redditors suggested completing those tournaments again and getting another platinum time, which I did, and it did give me my medals back, but once again, when I left the game and came back a few hours later, they were all gone.

Another thing I noticed that seemed weird to me is that, when launching the game, I got a message saying that, since the last save file came from another console (huh???), the game was going to restart using the previous save file.

I'm obviously not an expert at this, but I'm thinking maybe the save file on which I have 567 medals got corrupted by one of the numerous game freezes, and that it causes the game to constantly fail at loading it, so I have to always load the save before that one ,on which I still have 561 medals.

Anyway, I've been trying to find a solution since then, but nothing works... And since I'm on Xbox, it's impossible to delete any game files since the only ones that show up in the console settings are the user-created tracks, the game itself, and the 2 DLCs.
It would be pretty sweet if anyone could find a solution to this, since I'm trying to reach 580 medals, but I can't because of this problem :/

Any help would be very much appreciated ;-) Thanks
