It says the quest is complete in my Quest log. It also shows on the addon Questie that ive completed it as well. So when i went to go turn it in "Tirion Fordring" doesnt do anything. He Talks to me but nothing about the quest. Not sure what i should do. Need some help here. Dont know if i should drop it and do it again? or will it even allow me 2 now that its completed? Help pls.

Well if thats the case then hes nowhere to be found. So since i have it complete then what? Would be nice to get some help since im clueless and and quest is interesting but not fun to run over and over again.
