I went to Ngobbu first. However, I'm not certain if this a bug or just me not being able to find a way to progress.
I will try doing things in the same order as you did, and see if something breaks
Tested it, but can't seem to replicate the error.Entered Norfwich -> Talked to Ivan in the Tavern -> Rescued Ngobbu -> Rescued the Noble.But I'll add in a way to progress the quest next update. And I'm gonna have a look in the editor to see if I can put in some safeguards
