I have version 2.4
I have see only scout, fighter and harvester ships. I get defend base mission, terror and chrash site.
Never i see a Alienbase or a Battleship. I have shoot down hundrets of UFOs. Sometimes i get the message "Alien Activity in ..." I scout the region, but never i found something.
Is this not integrated yet or is that a problem of the difficult level very easy?
Oh... and now no new ufos will spawn. I have think in 2.4 spawn the UFOs randomly
