I completed the 1,000 points for November on the 2nd and looted the reward chest for the Arsenal: Cosmic Weapons Cache. I missed the note when Blizzard added Seetheras and Gorridar to the Cache on 4 Nov, but saw it this morning (5 Nov). I went back to the Trading Post to collect them, the Aventurer’s Guide says I have two uncollected appearances in the final reward, but the chest is not highlighted and I cannot loot anything else. I tried on multiple characters with the same result.
Bug? Or workaround to collect the new rewards?
