[V18 Stable from Steam, on shot CTD]

On a Corvette mission on a desert map firing a sniper from the second story of a building and hitting a Harridan soldier causes a CTD, I've done it twice now, I'm not sure what part of that particular action is causing the crash, firing at the soldier from the ground floor hasn't caused a CTD. I also noticed i was not able to get to all of the second floor of the building, a room with stairs leading to the roof was inaccessible even though there was a door to the room on the floor.

[V18 Stable from Steam, Rock not counting as cover]

On a ground mission on a desert map a Cebillian shot and killed one of my soldier by firing diagonally through one of the large square rock structures, when i moved another soldier over to the rock he had a clear line of fire through the rock back to the alien as well.
