This is very frustrating. After you grind that big map, you just want to finish it off and have your reward. I had to repeat the final game about 3 times because of the server error, it wasn't marking it as completed.
Then, when it finally marked it as complete, I didn't received the Pujols card or the 10 packs, nor the final prospects pack.
I submitted a ticket but you know how much they take to resolve the issue... this is frustrating af.
