Theres HQ mission generator, which is supposed to receive an update soon. Until then though it doesnt work for multiplayer (but will be great for it when it does), and you cant use the F-5E-3. I agree though, Liberation was a great idea and I absolutely loved it but this bug breaks the whole thing. To fix it one would only need to change one number in a line of code. If you look on the issues on the github for it, what is needed to fix it is right there, but Idk how to run it from the source code :'(.
