The Poppy Field Mission

You have the option to bring Pomor the gear of the stalkers that fell asleep in the fields. In exchange he will reward you with the the location of the cellar. I collected all of the gear from the markers but I can’t progress his quest line option any further. He still just says that he’s marked the locations on my map.

Edit: To anybody as dense as me and are having this problem. Don’t clear your inventory in the middle of this quest xD he wants those broken guns!
