Spoilers, Natch, and a bug?

I've successfully defended the Tywom at the Mu'kay trial. Got the meat puppet, used it,  did lots of things, only to later realize I still had the quest outstanding. I had to tell the Tywom home world of my success; that's the only step in white. But at Tywomia, I have no dialogue tree to tell them.  Any ideas? Is this a bug? I did things way out of order... I've unlocked the origin portal and fought a handful of the creatures who came out (x-whatever)  but still haven't completed the Drakend quests... Oops.. Possibly lying that's holding something up? 

Help!
