Bug on Grizzly Hills

Hi there! When I tried to do this quest "A sword fit for a champion", I went to Grizzly Hills and found that this whole area (Ashwood Lake, Westfall Brigade Camp, Ursoc's Lair ...) doesn't have any NPCs, animals, etc. So I can't complete this quest, and more importantly, when I tried to go to Lake Ashwood, the game automatically returned me to Amberpine Lodge. I do not know why! Someone had the same bug?

Check the bug tracker and if there is no such issue reported, please make an extensive report of whats missing.
