MQ seems bugged at very end

[Escher]

Greetings everyone.

I just finally got around to finishing up my MQ today. I got my Unfolding Portal as asked by the Lich and was sure to take it back to her and let her set it up for the Behemoth; however, when I went to the Behemoth and gave the item to him so he could be ported away, he simply gave the item back. I've tried hailing him but he does not talk to me. I also tried simply clicking the item to see if it was a "clicky effect" but that did not work. Am I doing something wrong, or is my quest simply bugged?

Thanks for any help.

You're probably trying to use it on the wrong Behemoth, she wants the one inside Heartland Undercaverns.

That would be why. I figured I was supposed to use it on the same one from the beginning of the quest. Thanks mate!
