Uhm... why am I running into pacifist invading aliens? They do not fire at my soldiers, ever. They shoot civilians and local forces, but not Xenonauts. I'm more than three months into the game (January 1980) and pretty much all I had to fear from aliens was reaction fire (well, occasional friendly fire as well). Is it just me or is the AI not working at all in this version?
