So, we wanted to start Abrams quests in Junkyard, after having put them off for quite some time (having finished Gorskys protectorate shield quest; Now wanting to go and blow up the Protectorate Elevator for the Free Drones), Abram doesn't have any option but "End Dialogue" now.
Possibly this is the same issue that had been there with some other characters before? That saying you will come back to their proposition removes all dialogue options the next time you adress them?
