This is the Class quest "Brawling Lessons" you pick up from Hunward in the Traders Wharf in the Wildwood. I got about 2/3 done with it and then today when I logged in it was gone from my Log. Has anybody else experienced this?
Of course, the help ticket portal is down, currently, so there's no help to be had there.
you may also want to check that there was not some kind of timer on those quests and you simply waited too long to complete them and they reset. this may be true if they were dailies although they should not have disappeared just because you didn't get it done...hmmm...*scratches head*
