I've been having a weird thing lately where if I take certain Garrison apexis dailies before I start my Tanaan ones, they complete. I first noticed it when I picked up the Pit daily and came back after my Tanaan dailies and noticed it was complete. I know I definitely did not do the daily but I did kill some Iron horde. I didn't think much of it, except lucky me.
Then I took the a different daily (it might have been Shattrath daily) and I went out to Tanaan and when I came back THAT was also complete. Is it because of certain mobs that are named the same? Or there are other shadow council mobs around?
Anyway, that's one I have to ask the Devs. I don't want to think I'm cheating some game mechanic or something. Or maybe one of my readers can tell me why that's happening - perhaps it's MEANT to do that! I won't complain about the free gold or the free apexis crystals :D
