Sorry to post a discussion, but I can't comment and I think the author should see this.

TLDR: The psychic drone can't trigger without a colonist at the map, but it keeps trying to, creating an endless loop that makes the game run at 1 Frame Per Minute. Also there's so many of them during the Prisoner Demand raid, it's laggy.

I raided one of VOID's Neurotonin stashes and managed to down 1 of their members. I got the Demand from them to release the guy and I tried to be smart: Instead of bringing him back with me, I erected a prison right there, harvested his implants, and dipped. I didn't abandon the map because even though I have no use for the guy anymore, I didn't want to do what they told me to.

When the raid came, none of my colonists were at the map and I got loops and loops of errors and the game run at 1 Frame Per Minute. At first I thought it was some drop pod errors as my game tend to lags during drop pod raids. But I found out on the debug log that it was something about Psychic Emanator.

So I dug through the VOID mod files and found out that these events were supposed to trigger during their retaliation raid, and upon further searching on the internet found out that Psychic Drones create endless error loops in a map without colonists. It was a problem reported to Tynan back in 2016, when the colony died and the psychic drone tried to trigger.

When I used dev mode to send 1 of my colonist to the map instantly, the Drone and the rest of VOID's events spawns normally.

It's still super laggy though, with how there's like 1000 drop pods trying to squeeze into the map. At that point I knew that the raid's not supposed to be beatable, and if you CAN beat it somehow, then you know you've already won the game.
But still, I just wanna say that I want V.O.I.D to kill me with normal means, like beating me to death and harvest my organs. I don't want them to kill me through lags :(
