A bug in the military warehouses (S.T.A.L.K.E.R.: Clear Sky)

After talking with the Forester we need to return to the military warehouses and talk to the mercenary (which was supposed to send to the members of the military to dislodge and send a radio message lost group). So, in the village of a group of mercenaries there. Specifically that NPS not. With nowhere his body. Please tell me how to fix it?
Tried to reboot, restart the game, kill the mercenaries to kill members (just in case), but the NPC never showed up.
Mods not installed, the game is licensed.
