Since I don't know exactly why it's not working for youI tried it with fully equipped changing clothes unequipping and equipping the gun several times, there also seems to be a bug in the inventory few items are copied and when i try to discard them i get bug popping up so maybe it has someting to do with the invenory.

and if that still doesn't work, I've attached my save at the point where you go on the mission.
