I am having this problem too. the buff is not working.
Still nothing from staff on this? Now I've got the broken wizard buff on top of broken my npc shop discount.
nothing still and i have had both of them for a couple days now
Same issue. I might have just missed it, but I may not have gotten a random event banner for it too.
The buff is also lasting waaaay longer than it should.

Having the same issue, but 3 hours after I got the buff, the extra quest was available to me as of a few minutes ago. Keith did post on another bug report about the shop discount buff that it's being looked into.
You can do the extra wizard quest now, but that buff doesn't disappear after questing, and the timer is still increasing.
Originally got the extra wizard quest buff on Thursday 12/9 (before doing wizard quests that day) and was only able to do 10 of them (and received both 20 and 50 point wizard tokens for the 10th quest). Then yesterday (Friday 12/10) I was also only able to do 10 wizard quests early in the day, but was able to do the 11th quest shortly before midnight - and did get both a 20 point and 50 point wizard token for that last quest (as well as for the 10th quest earlier that day). However the buff did not go away - even after doing the extra quests and today's quest reset so wound up doing 11 wizard quests today and received the bonus 50 point wizard token only for the last (11th) quest. And yes, the timer continues to increase as does the one for the main shop discount. Hoping this information helps to figure out what is causing this error to happen.
Did my quests and got the extra one but the buff still says I have 1 day and many hours left.
You've completed 0/12 quests today!
1 Extra wizard Quest!
Expires in 3 days 11 hours 50 minutes 50 seconds.
I did get two buffs within this 3 day buff glitch and the timer still going up
I got an extra Wizard Quest on Saturday or Sunday (I think) and it's still there. I didn't pay attention to it yesterday but I noticed that I still have it today and it hasn't gone away.
I'm kinda worried about this glitch/issue... Ok so the quest from the buff finally got added but what happens when quests roll over... what if you still get the buff added to your next set... would it be safe to just do your usual 10 (or 15 depending on GA) quests and avoid the 11th/16th? Not sure if it'll carry over but in case it does...
Just tossing that out there. [edit] Yup.... /11 wizard quests.... I wish this got fixed.... :( I will do my 10 and leave the 11th alone.
You've completed 12/17 quests today!
This was the same thing as yesterday. I did the 2 extra quests because they were from the 2 original buffs. Not sure if can do it again today or not. Doesn't feel right to do so.
Mine won't go away since recieving one yesterday. Won't do the extra one since it's a current glitch.
I am having the problem that the buff wonโt go away. At first it was showing a buff but no extra quest. Now it shows an extra quest that simply wonโt go away.

I just realized I still have my extra quest buff from yesterday! And now it says "Expires in 1 day 2 hours 35 minutes 44 seconds." Is this buff suppose to be running this long? I did get the extra quest both days.
