After finishing 20 waves of Awakening the Machine I did not receive any reward from the 4th (biggest) chest or someone else looted it, not sure what happened - it just vanished when I clicked it.
Received a cosmetic item in the mail, but no Valorstones or anything else.
Many of my weekly quests did not reset this week. The Awakening the Machine weekly was not there, the theater quest was not there and the weekly quests that were there did not reward keys for the delves.
The US forums have lots of posts about weekly quests not resetting but I can’t find anything on the eu side, but it has happened to me today. No keys and very few weekly quests.
I have the same problem, the 4th chest that I opened just disappeared when I tried to loot it. Nothing in mailbox and nothing after relog.
