Hello. So basically, I did the quest to go to Grizzleheim, I went to Grizzleheim, but now it says I need to go by boat again. This happened after the update and it wouldn't be a problem except I can't go by boat. When I talk to the guy he tells me what to do but nothing happens. no boat ride. So ye. Help?
You go to Grizzleheim by going through Bartleby, the big tree in Ravenwood. You only take a boat the very first time you ever go there, as an introduction. After you do Baldur Goldpaws' introductory quest and pass level 20, Ambrose should have summoned you and sent you to Grizzleheim.
Wintertusk does require a boat, but you can't go to Wintertusk until level 40, minimum, and after you complete the Ravenscar portion of Grizzleheim.
In short, go to Bartleby or go through the spiral door at your house. Select Grizzleheim and go.
