Yep, we know about this error. :o Will be fixed soon I hope. @XComVic: It's possible that there are 2 aliens in the upper floor of the japanese house. Are you sure you checked out all corners of the room? Alien may fire at you and hit the terrain. They suppose if the can see you, they can also shoot you. I think it should be not a big issue to fix that. We will also change this civilian-spotted-stop-thing. And there are a thousand other things we plan to do...
