During one of the missions for the Evidence Board questline, I had an enemy fall into an unreachable zone [spoiler]under the stairs before the memory area (after killing mini-boss)[/spoiler] After not finding a solution to reach said enemy. I had to "abandon activity" and returned to orbit. Both the in-world marker and the quest in the quests tab were gone. I cannot grab the next step from the board and cannot load back in to re-do the previous and begin the questline again. Quest is not in the abandoned quest kiosk either.
