I have completed the Zodiac questline all the way up to the fourth leg, "A Treasured Mother". Upon travelling to Mor Dhona the questgiver, Brangwine does not display an available quest. It used to have the Morib Motivation quest, which is missing on my screen as well. The NPC only has a short dismissive line of text when clicked.
After completing the quest "Method in his Malice" I did accidentally accept the quest once more and promptly unaccepted it before traveling to Mor Dhona. I do have all the appropriate quest items in my bags.

Did you double check your journal log to make sure there wasn't an open quest still that might be interfering? Not the on-screen list, but actually open the journal and check the currently open quests?

Oh, and it may sound stupid but is important to rule it out... Are you properly equipped (as in , on the right job)?

I did but thanks

Yes, I did do all those things but I appreciate you taking the time to suggest it! ;) Feeling very frustrated

Are you sure you don't have Morbid Motivation active?
