Yesterday for a period of time this reward box from the Last Hurrah crafting spark world weekly quest was rewarding low level greens (ilvl 350 for me) instead of S4 Champion gear.
I’ve run this weekly quest on other characters before and after this period of time, and did not experience the issue outside a relatively short window yesterday.
I’ve submitted a ticket, but from others’ responses around here, it sounds like it will not be something CS is willing/permitted to reset or provide a replacement for.
I don’t think this issue effected as many people as the TW cache, but there were plenty of people here and in-game yesterday experiencing the same thing.
I hope there is a similar resolution to the TW cache for the Awakened Storms cache.
EDIT:
Ticket answered
We have received multiple reports of this happening to other players and I can confirm it is not working as designed. Thankfully, our developers have since fixed the issue that was causing this problem
We are unfortunately unable to assist players with replacing random item rewards or resetting weekly lock-outs.
Seems I’m out of luck, unless the dev team can come up with a mass fix for those effected.
