Issue #25740: Dejen does not start the quest "Hunting the hunter"
This is from the wiki:
Mission fails to start, ever. Dejen does not initiate quest dialogue.
This can be seen if it applies by typing showquestvars DLC03AcadiaM02 this will show the quest as stopped if the glitch applies. It can be fixed by using the command SetStage DLC03AcadiaM02 10. This will start the quest start dialogue.
My quest is indeed stopped, and using this fix I can finish it. This bug is appeared to be widespread. I was on Fallout 4 1.10.120 and UFO4P 2.0.5b.
I did this quest last in the entire DLC, I haven't talk to Dejen until now. Because of this bug I did not know this quest exist until I seen it on the wiki. I suspected the majority of player don't know this quest exist because of this bug.
