The Trader at the Flea Market was missing
If you mean the trader in the basement, are you sure he wasn't simply asleep, or chatting with the other NPCs on the upper floor? Also, when a location is under attack traders will temporarily disappear. It could also be a bug, of course.
Also the other person that gives you the some missions was missing.
Wild Napr? Can't remember is it's possible to have him get killed.
I also ran into the problem that Van will not take the flash drive for upgrading the shotgun, all blue Flash drive (pump mechanism for combat shotgun).
That flash drive might be for the Agroprom technician.
