Is the 'A Cold Front Approaches' quest bugged?

[Hypercapnia]

I'm unable to turn this quest in. I can talk to the guy in the hut but the option to complete the quest is greyed out and his question mark is grey, not yellow. Sorry if this is the wrong place. I can't find where to report bugs.

Hi, for those who are facing this problem, you need to enter the building where Goblin is standing, then you can turn in quest.
