So, I was doing a couple normal runs today, for my last haste trinket.

My first run, I unmounted all the 3 bosses in p1, but it just would not get to p2. All bosses were on the ground, had my slaves on each of em, keeping em from mounting up again. So, i reset the instance, and everything runs smooth. After that, the same bug happen over and over again, i would get them all to unmount, but the event didn't advance to the next stage. I also tried to let one of them mount up again, just to kill him, but that didn't help ether. So, then i unmount one of my slaves, to manually cast this piece of shit to death. Nope, just would not advance. This happen 4 times, until i got the "to many instances recently! message.

Yes, I'm 100% i did reset the instance, and the instance was set to normal at all times. This also happend yesterday, but only once.

Any idea whats causing this bug?
