Im using this build from muton
ufoai-2.3-dev-28896-Debug-pentium3-O1-sse-7z-small-win32.exe
On the industrial map mission where ufo landed if an alien spawns close to your troops on the first round and you shoot them the bullets go right though, this includes area effect weapons like nades as well. I had to end turn wait for them to move before they are hittable again.
