Yes, I'm having trouble getting through:
1. In the last 20+ hours of the game, I have not found the "Alien Sensor" (screenshot 15, which should lead to a new hyrid ship.)

2. After researching Psymorph Commander, he had to give a new research. Which he successfully did not give, thus "Kydonia or Death" is not possible to study. (screenshot 14)
3. 3 types of ships do not appear at all. Assault, Supply, and Battleship.(screenshot 16)
4. Invalid mission name.(screenshot 17)
Save for convenience to check
