zul furrak

Ran zul furrak earlier today and did the 1st mini boss (in the cave)
killed him but the 3 mobs adds that spawn when he dies run to the back of the cave and can't be killed, also couldnt leave combat.
ran out of the instance and back in, got back into combat on the next lot of mobs and again couldnt leave combat. had to end up resetting the instance and starting over

Yes that's a bug that's been around for ages. There's likely a bug report that's been made already somewhere, so upvote it if you can find it?
