Another oddity i just happened upon was a medium-sized megapol craft that i shot down and assaulted with gals. Everything was going just fine, i was taking cover behind my ship and killing wolf-men pig-men and the big brutes left and right. Then at one point when there are no enemies near my ship, i send one team forward to assault from one side while another takes cover behind the ship, out of sight. I click end turn, and my team that was taking cover spontaneously blows up. That whole team is severely injured and one of my high-health gals in warrior armor is even killed outright from full hp. Neither me or my enemies had thrown a grenade, and i hadn't primed and dropped any explosives either...so what happened?
