I spent alot of time (several hours) trying to Destabilize this in alot of various different ways in a different areas. Then I decided to take a break for a few hours. I went back. I went to my usual place 55, 66, click once Voila! It destabalized. I’d say it took a long time for it to align itself for that part of the quest to work. In the future, with other people, ya may want to consider this.
