I was playing MP yesterday, trying to get the Card packs. You know, like ya do.
I was cutting it kinda close with the third one, and completed it with ~5 minutes left before the packs for the day refreshed. Came back after it unlocked to claim it, and after I did, I had to wait 24 hours to start the first pack.
In other words, the game thought the third pack from "yesterday" was "today's" third pack.
(Didn't take a pic of it. Sorry)
