More on this. Not complaining, nor unhappy, but I got the cache today from “Ashava the Pestilent”. So, now I am stumped. Is the game half broken? Has Blizzard fixed it?
Update: 08/09
Well, well, well. From the latest patch notes:
“Fixed an issue where the Weekly Reward Cache for defeating a World Boss would display as available if there was an active Whisper for defeating the boss, even when the Cache had already been claimed previously.”
That had to be it, I see no other explanation. Nothing lost then, carry on! Phew!
