Issue #27215: A type of robot in particular, when it dies, is shot in the air
This particular robot (with all these variants) -> https://fallout.fandom.com/wiki/Swarmbot#Cybermech_swarmbot
When you kill him, the robot literally goes off in the air, 99% of the time you can't find it, sometimes you can get to see it through the air and get lost (once I even found it far away from where I had killed it, from chance xD).
He always does the same, you kill him and he is released, I think it is a problem with animation at death? There is something wrong, and this has always happened to me, it happens to many people, I don't know if this has ever been reported.
I invite you to do the test, spawn these robots and kill them, you can check the problem yourself.
