Human AI can see enemies inside fog. When I was defending heavens, heaven defenders that were uncontrolled by me, shot tritons that were inside mist. How? I couldn’t even see them until I was like point blank.
Human/Pandoran Ai can see through stealth. I was shot at many times when my infiltrators were stealthed.
Human/Pandoran AI can shoot right when they spawn as reinforcments. Considering their movement is limited to few tiles, they also should not be able to shoot. Heck I was even shot at through the entire map even if the reinforced unit was the only unit on the map. Example Synderion steal aircraft. My soldier was on the western part of the map, just left of the ship, enemy sniper spawned it on the central eastern reinforcent and directly shot my soldier. Double the pain it was a head shot.
