Update: I continued with the release version engine and got stuck in the Dilgar mission, because it is much too hard and in a completely unrealistic way too. Even after setting the enemy fighter AI to rookie, the friendly fighter AI to elite and removing the EA missiles, which the Dilgar cruisers were firing, all Vorlon fighters die within minutes, myself included. This makes no sense whatsoever because the EA could have never beaten the Dilgar that way and they did in the show! What could be the reason?
Also the whole setup still looks very strange, because all ships are lighted red, although the nearby moon looks normal and the biggest nebula is blue. How can I change this? And last not least, why is the release version engine slower than the debug one?
