Kolitra Deathweaver NPC dissapeares once you complete "Brothers In Death" quest .
If you are fast enough you can probably get the next quest from her - Bloody Breakout, but other than that I don't think she respawns.
Can someone share their experience with this?
I see there are already two reports of this in the Bug Tracker, so I don't think this needs more.
Also I guess we can just port to Stormwind/Orgrimmar, but that's not the point here...
