Ok, this just happened to me so I didn't take any screenshots on this, I will tomorrow when the dailies will be up again to test. Basically I did my normal routine of dailies, Hodir/IC/Tournament -- I ended up 23/25 dailies and WG popped.
SO, I thought to myself, mine as well go do the last 2 there. We were on Offense so I grabbed the 3 quests available by the Flight Master in WG (Horde side) when match started. That is Victory, Kill 10 alliance, and the other one(can't remember what I did lol -- defend siege maybe?) Anyway, we win WG and inside the base I turn in the first quest and it ticks to 24/25 dailies. I turn in the 2nd quest and it doesn't count towards my counter. I turn in 3rd WG quest and it still doesn't count towards my counter and it says 24/25 still.
I just went and did the cooking daily real fast to see if it was bugged completely but it quickly brought me to 25/25 dailies done. SOOO -- this may be completely useless and be a one time thing I am hoping that it may be possible to save those 4 WG dailies you can do til your 24/25 dailies and be able to end up doing 28 or 29 in one day.
I hope this made sense.
