Quest Issue: Grim Tiger's Revenge

[Passenger]

Grim Oakfist in Kithicor Forest is not responding to hails or offering the quest Grim Tiger's Revenge even at warmly faction.

Also, Grim shares a spawn with Brollus Hoost and Tallyn Starwatch. This appears to be functioning as expected, but whichever one of them is up doesn't actually despawn at nightfall with the rest of the living NPCs in the zone. Instead, whichever is spawned remains up until the next morning when the undead despawn, at which point 1 of the 3 will respawn.
