SAB - Powered Shoulders Box not dropping?

[Nightbus.8640]

Something seems off with the meta "Super Adventure Box Nostalgia (Annual)" achievement that's preventing me from getting the Powered Shoulders Box.

1. When the festival started, I played through World 1 & 2 on normal mode, and saw that I got the "(Annual) World 1 Classic" and "(Annual) World 2 Classic" achievements as expected. I also got "(Annual) World 1 Warm-Up" and "(Annual) World 2 Warm-Up" which was nice, I didn't recall in the past that the higher difficulties would retroactively complete the lower difficulty achievements. But maybe this is part of the issue?

2. Now, even though I had 4 "Annual" achievements unlocked, I didn't receive the Golem-Buster Weapons Locker despite the fact 4 achievements should clear the tier 1 completion.

3. I went ahead and also completed "(Annual) World 3 Testing" and "(Annual) Flight of the Bumble Pugs" - but still no Golem-Buster Weapon Locker, OR Powered Shoulders Box.

4. I tried going back and completing World 1 on Exploration mode to see if it would re-trigger something on the achievement side, but didn't see any change and no drops triggered

5. I completed "(Annual) Zone Running" and finally got the Golem-Buster Weapons Locker to drop.

6. I went and completed "(Annual) World 1 Challenge" to see if that would finally trigger something, but still nothing came through.

I'm now sitting on 8 Annual achievements completed on the Nostalgia list. I guess i could try and complete the last World 2 Challenge achievement, but I really don't want to suffer through that on tribulation mode if I don't have to.

Any ideas?

You could check the widget in the Wiki and see if there is any difference.

You could contact the CS Team via the 'Support' link above/below and discuss the issue with them.

Good luck.

When I did the achievements this year, I had to do Exploration and Normal separately for it to count. If you got both with one run, then I would guess that something happened with that to bug out the achievement for you. I'd contact support.
