Hello, EA,
A glitch prevented me from getting the diamond player.
I labored on the Trick-Or-Treat events for an hour and a half, and used up all my 3500 popcorn on the blitz. After starting around 9:00 PM, I was halfway to a diamond player when a glitch at around 10:30 CUT OFF ANY FURTHER EVENTS; only the blitz event (with its meager awards) was accessible. At 11:59 PM, the events finally appeared, each with roughly 20 seconds remaining before they expired.
I can't afford to spend real money to buy a diamond player, so this was my only chance in the entire year to get one, and I could have got it easily without the glitch. The same night, a similar glitch ended one of my drives in a LvL tournament, just as a got into the red zone against an 89 OVR defense.
What gives?
