I was on an RPGLIKE/explorer run, got the golem unit, got into section 7 and put the live sigix into the exoskeleton. After some heavy combat in the section, entered research with the sigix warrior at 40% exoskeleton integrity. Then after being constantly delayed by chasing investigators and constant ARC's, that brung the sigix warrior to 20% exoskeleton integrity, On some random turn the game froze and then shut off. I restarted it multiple times and always after some time, it happens again.
Also I had no aoe weapons at the time, probably cocntributed to how much it took to even get to research.
