The Dreadblades - Bugged, can't finish quest

[chron]

I can't finish quest for The Dreadblades (Outlaw rogue) because i used heartstone instead of taking the Gryphon at the end of the quest. Meaning I am bugged and cannot take new artifact weapon quest. I was at the point of "The Dreadblades - Fly to Dalaran"

Character: Chronrogue
