Disabling drone with Trojan Virus perk while under concealment breaks the mission

[Gerk]

Happened twice now. Reproduction is as easy as the title's instructions

The drone takes damage, things go into weird alert, but you only get 1 turn of combat music.

Makes the enemy turns take an inordinately long time, except no pod movement happens.

Despite everyone being in concealment, Reinforcements will be called eventually.

I've also seen this happen with troopers that walk through fire in the fog and anything else that causes damage without giving Advent a direction where to go. Your repro sounds the most reliable though.

Seen this sort of thing too. Had a mission to destroy an alien transmitter thingy. Had a small squad go in to stealth up and nuke it. Ran into a drone. My specialist controlled it and sent it off to an away corner where trojan killed it. The patrols I had been watching for a gap to slip past all stopped dead and nothing moved again until I went loud taking out the transmitter.

This sounds like a known bug where of a pod activates with the squad concealment active the entire AI locks up.
PI couldn't fix this bug without otherwise making every pod leader flank itself on activation
