Last night I logged on and took Tumunzahar on a tour of Kalimdor. The buckets across the continent were all I needed for the Hallowed achievement. I stopped along the way once or twice for some pet battling or Archaeology (which is now 525), and then finished up with the last Trick or Treat bucket -in the Exodar (once I found the darn thing). That means I’m “The Hallowed” now.
That’s the shot right after I got the last bucket. Now, if you do a mouse over on any of those in-game, it shows a completion date. However, as you can see the entire meta is showing incomplete. I reported it as a bug and just shook my head and went to bed. No point worrying about it just yet.
Sure enough, first thing this morning when I popped on quick before work, It had been corrected or sorted itself out and I be a Hallowed fella after all.
