Bug with Inheritance Quest - NPC Gumbah

[Alhanelem]

This is the quest and people say you can cancel them but I can't. It shows up under Bastok Mission Inheritance (Ground Strike Quest) and I have even gone as far of completing almost every quest in the zone.

Talking to Gumbah doesn't yield any options. Maybe because I've finished Voracious Resurgence which he was apart of... Either way I'm stuck. I think it is just bugged for me.

Well I thought I was implying this, but I'm thinking you have a different WS quest active that you've forgotten about. I wasn't suggesting you talk to the quest giver for the quest you're trying to do, but rather with the other quest givers you might have an active quest with- as was stated, only one of these quests can be active at a time.

You might be thinking you've never touched another one, but I'd like to ask that you check the other WS quests anyway, as unless you show that you've completed all of the others, it's still a possibility even if you don't think you have.

People post here at least once a week saying a quest is bugged and like 199 times out of 200, it was some sort of overisght, either a skipped step, quest was already completed, traded wrong item, another quest conflicting, etc. etc.
