Can't get the last two weapons

I can’t get the last two weapons, the Angel Wing and brass knuckles model 3. All the wikis say what is bought from Emil when he passes near the resistance camp, I smoked Yandex, Google and YouTube for a day in search of information on how to do this. He constantly rubs me in his initial route near the entrance to the desert. I talked to him and bought / sold and killed (passed his square), etc. All methods don't work. Once, playing as S9, it somehow turned out to take him to the route of the terminal "near the factory", but he didn’t give weapons there either, then he did a couple of tp back and forth and that’s it, he again returned to the desert entrance. I ask someone who knows how to lure him out, and indeed to unstick him from the entrance to the desert, to help. I'm already exhausted, there is one ending left with copies of Emil, but I can't do it because these two weapons are missing. In general, HELPP!
