I have been out of town the past few days, so haven’t been able to play Halo on the Xbox, so I have been logging into Waypoint to open my Daily Login pack, as I have been able to do before. Yesterday and today I have tried multiple times, but it keeps saying I have no unopened packs? Was there a change made to how this works recently?
Same here

Yeah I just checked today, not there for me again either…
Its usually awarded when you log into the game in XBL. That said, I have had it upon log on to WP 3 times.
