Aliens would shoot at your troops with reaction shots only. They would never target your troops during their action phase. Once I figured it out would suppress one then run troops right up to them. During their turn would just crouch and never shoot. If you moved next turn they would then shoot you.
Great job on getting out a hotfix, made all the difference in the world. Hopefully can fix them seeing you all the time shortly, but between the two options I will gladly take this.
