STAR CARDS WONT UPGRADE!!!!!!!!

Hey @EA_David, I have a bad working theory as to the source of the bug, and how it's related to the 'REWARDS' bug. Other players may need to confirm. I noticed this started happening after I achieved the 'PLAYED THEM ALL' Career reward. That "locked" my ability to claim additional career rewards as well as upgrading cards. Since PLAYED THEM ALL's rewards are meant to be crystals, and crystals are no longer in-game currency, could that be what is causing the issues? Arcade rewards are still unlocking normally. Take a look at it, I have a good feeling that could be the source of these server sync issues since it's pointing to a reward (crystals) that is no longer valid in the game.

One more update, I leveled up to 11, but same issue. I still can't upgrade, which is making me suck even more than usual. I need all the help I can get. Any assistance would be most welcome.
