"Subtle Matter" mutant spawn bug

[lacunaserenity]

I'm on the mission "Subtle Matter" and I went through the basement and killed the 3 mutants down there and there's supposed to be a 4th mutant (poltergeist) above in the main building but he doesnt spawn so I cant progress at all.

I did the console command to manually finish this mission and start the next one at the Comms Center and went through and finished it but no future missions start now so I had to revert back to the "Subtle Matter" mission save but cant progress because the poltergeist will not spawn.

Any suggestions on how to resolve this without the console command to finish the quest? I dont want to have to figure out the codes to manually start literally every quest going forward and am stuck. :/

Have you been in Kaymanov's office by "googling" the door code before the mission started?

I was much earlier in the game when exploring, but the mission is all completed except the one mutant isn't spawning for the last part. NPCs have left as scripted. The basement mutants spawned fine, just not the 4th up top.

i was stuck on this mission because I didn't realize you could kill the poltergeist. Yes, there is a mutant poltergeist in the main building somewhere but he is very difficult to see. Maybe he's stuck in the corner in some room or something.

I thought so and searched every inch of the inside and even to the surrounding yellow area outside the building. My compass is never red or alerted so no enemies closeby. I have even searched every inch of the X15 lab underneath and nothing alive is left either.
I may just be SOL on this playthrough.

Praying for you brother. I feel like for this mission they need to show you on the HUD where the last monster is, like they do on other missions

just a heads up for anyone its definitely the poltergeist in the building where his office is its hard to trigger, but once you trigger you just have to find where its hiding a couple times because it moves around shoot it a few times it will flee find it again etc. took me way to long to find that damn thing

I have same problem. I killed Poltergeist but there is no other mutants anywhere. Mark points me to outside main building but on this place is nothing. There is no creature anywhere. No sound, nothing.
I tried to find a way to some underground or tunnel bud there is nothing around. I tried to load previous saves but I have the same bug.

There are 4 burgurs or whatever they're called undearneath that you need to kill. They're the short, fat creepy cloaked monsters that have psi powers. Check outside behind the building, there will be stairs going down and then a door going to the basement. Check down there and like I said, there will be 4 tough monsters to kill

If you havent figured it out yet or if anyone else needs help... This is what happened to me, I went in the main round building and used the code (killed poltergeist first), then went down in the basement and found only 3 of the hooded dwarf ♥♥♥♥♥. Circled around multiple times and could not find the 4th. Did a ton of looking into it with no solution from steam forums or reddit etc... Eventually while exploring for maybe the 7th or 8th time I found the lil ♥♥♥♥. When you enter the corridor from the elevator shaft where you encounter them first if you take a right and go down all the way theres a "prison" gate that cannot be opened from this side. Far down the hall past this gate I heard a noise and decided to toss some grenades (if youre standing against the gate the grenades wont bounce and will hit the bastard) look for a blueish, purpleish hue that surrounds these enemies. Killed it with a few nades and boom quest triggered. PS there is likely a way around but I havent found it yet.

Burers

There are 3 burers below , kill them and nothing will happen unless you kill the poltergeist . The poltergeist needs killing above for the story to progress . The poltergeist will only show itself once killed . It can be killed before or after the burers but you won't progress until it's killed and just wonder aimlessly around cursing a game glitch .
