Hi guys I notice something, I don't know if it is a bug of the vanilla or yours,but it happens that when an alien is stun before you reserch the stun weapons, when you finish the mission, I'm not able anymore to discover alien biology.That's ruin my game beacuse later it ask you to capture an alien officer. But how ? If you don't have the stun rod or the stun granade ? Anyone is able to fix that ?
Thank you
