A dev could be working on it at the moment, but you can make a thread in the bug and technical report forum to see if others have the same problem.
That way, if it is a problem many have, the devs will be pushed into updating it once the problem gets to them.
Have you collected the stuff needed to make the boa? It might be that you don't have everything for the quest to be accepted ( red words show up counting down/up then say go to NPC to collect your reward) you have to get them in game and anything thing in your inventory before hand does not count.
If you have done this then report it in the bug forum and/or in the bug sticky found at the top of this forum try and give as much information as you can to help the Dev's
For now I'd say leave the quest and move on to something else.
