Fully second that, this is the most annoying thing for me so far. Civilians running into an UFO I am preparing to storm, constantly trying to position themselves next to aliens or directly in the line of fire, or even to block doorways or windows.
Initially I tried to protect them but by now I honestly treat them more like mobile destructible obstacles, as that is what they seem programmed to be.
It would be really great if they had a simple sensible logic like "try to get away from aliens and behind the Xenonauts" or "hide in a corner somewhere".
