Hi Stalkers, I'm getting trouble finding the bag, any hints? I just came across some tough monolithians but no sign of the bag in the reference location. Is there something I did wrong?
The bag should be on an NPC called something like Capt. Goncharenko (the name changes slightly between games), who should be in a small encampment by the outer fence almost directly across from the Sarcophagus entrance. It should be easy to find as there are a lot of crates and a laptop among other things - oh, and a BTR may put in an appearance when you first arrive.
The Captain should be alive, and in my recent games he is the only living NPC in that area. However, he can die before you reach him (I once found his corpse close to the Sarcophagus entrance for some reason) so check any grey dots on your minimap.
If he isn't there, I have heard some people say they found him after visiting the Wish Granter, although I have only ever found him on my first visit.
As a last resort
you can spawn in the bag (ESC+S menu, Item sumka_arhara) and you should get a prompt to return to Sakharov.
