Farming Mt Hyjal for transmog, and I can’t seem to get out of the first camp with Jaina.
I deal with both main assaults, kill the bosses, then run out along the road only to hit an invisible wall.
Undead start pouring in to the camp behind me.
I did this before, but this is my 3rd or 4th time failing at this.
I thought maybe it was because I’d run out to the spawn point to kill the mobs, so this time I met them at the gate, but no dice – still doesn’t work.
Any thoughts on what I’m missing?
Do you talk to Jaina after the waves & bosses in that first area? That progresses the raid.
Yea I talk to her to start the first event, the second event, then talk to her at the end of the second – she then “Mass Teleports” away.
Ok, then that’s when you run to the next area to meet Thrall. Talk to him and it starts the next encounter.
Did you wait for the monsters to come to the gates? if you kill then right where they spawn it can bug out I’ve noticed.
Particularly noticeable on the Horde part.
Yea, I can’t get to Thrall. The wall blocks my path.
Oh dang. That’s weird then. I’d have to go through and see it to know. 
Yea, I meet them at the gate. Before I was killing them at the spawn site, and I kept having the problem.
And, yes, this is on a Horde toon.
Also, pretty sure I’ve left the raid and come back, but it was still blocking me. Didn’t try that today though.
