Exact nature of the problem, where and when it occurs and what you were doing at the time. (I followed and cleared the Northriver quests line. NPC Dragobas and his ship 'J.O. Morgan Knife' have been stuck at my PHQ since then and he never leave even after I got both protectyon sale achievements. You could teleport to the CEB 000 station and go to see them at science lab/dock. It seem very buggy since the part when it's required to submit modified ships for the racing. I got Dragobas infinitely talking the same sentence at first, so I reloaded and could finished all the quests line. But he never leave.)
Any possibly relevant changes you have made to your game, system, or software before the issue occurred. (None)

Just some update from my current save. I deconstructed the S/M fab and the J.P. Morgan's Knife ship was gone. This could not get rid of Dagobas from the science lab though.
