I'm losing hope that there will be a resolution to this issue (as several of you have mentioned). If memory serves, I've had this issue since release. For me, the NHL (Golden mini pack) collections have always worked. It's the Red/Blue, Junior leagues, AHL etc (or Silver/Bronze mini packs) that don't work. First acknowledgement of the Collection Pack Bonus issue on this site appears to be 9/16.
I appreciate the fact that the disasterous release of the Xbone/PS4 required the attention of the entire development team (I assume), but we're closing in on 50 days of this known issue. To put it simply, the game "advertises" if you complete such and such collection - you get X amount of reward packs. EA put this in the game. Their description, their game. Has it ever worked? Were they ever able to "create" Bronze or Silver mini packs? I get the impression that's the hang up. They hadn't developed the non-tradable Bronze/silver packs that would be rewarded for completing non-NHL teams prior to release.
If you drill on the "solved" portion of this thread, it appears the Mods were contacted by the developers and an effort is being made. To what end? Where on the priority list is this? Historically with the NHL series - game updates and tuners tend to dry up by the end of October (just my observation). That's why I'm concerned that this will fall thru the cracks. How many people actually want to complete the non-NHL collections now that you can't farm coins/pucks? I, for one, like the new reward format. My goal is to create an entire team of non-tradable players. I still need the big NHL teams (PIT, CHI, WSH) but this collection issue has significantly diminished the fun that HUT has offered in the past.
