Tzark not moving after Gravelings with Grast.
Your team will scream at you and ping the WP repeatedly, but when you got the chest and the WP is appearing, don’t WP. Wait for the conversation between Tzark & Grast to start, then only WP.
Frór (yes, with the accent!)
Just a heads up, nothing will be fixed anytime soon. They’re just now fixing bugs that have been around (and heavily complained about) for >1 year.
The usual work around for this is to have the entire party go all the way to the North end of the passage just East of the final boss fight. This should cause the NPCs to teleport to the party.
Or, just clear the gravelings. There aren’t that many of them :-P
Maybe it’s cuz his plan is stupid and it won’t work.
