Bugged quest: the sacrifices we must make

Quest Bug: “The Sacrifices We Must Make” - Ardenweald. Currently you are unable to complete the quest objective “Wagonmaster Derawyn saved”. The cursor changes to a yellow hand when you highlight Derawyn, but you can’t click him.

You are hardstuck at Ardenweald questing progression until this is fixed (this quest occurs at Chapter 2/8 of “The Groves of Ardenweald”

Can only be completed in a group.

Abandoning the quest and redoing it worked for me.
