@invencivel47 Cats are awesome.
Certain abilities require a nearby Target.Harpoon, Man's Best Friend, throwing a nearby weapon, etc.They will simply be greyed out or not show their hotkey if there is no valid target for them.
@king_kai_2002 Hey Kai, I don't know if you solved this yet, but I found a solution. Go to the area and then follow the road West. it will be a decent ways away you should find a single NPC along the road. I killed him and the quest progressed.
@king_kai_2002 I'm having the same issue.
