Lately I've been on a Pandaria kick working on the tamers over there (Spirit Tamers, Regular Tamers and the Fable Quests) and it seems the Fable ones are a bit buggy.
At this point I can easily kill any of the fables usually with a 2 pet combo yet several times I'll kill them but it won't register as a kill (I have to log out, log back in and kill it again).
Yesterday after finishing all 3 fable quests, the return quests were marked at the quest giver over at the Alliance Side (I'm Horde). When I got to the Horde it showed them all as blue '!' even though my Quest log showed ready for turn it. Like a dummy I abandoned one and lost the quest but the other 2 I saved when I yet again 'logged out, logged back in'
Sending in a bug notification about the first one since it just happened, but was curious if anyone else was seeing odd bugs with the Fable Quests.
