I have even seen the addon payware packs get it wrong when they used the same mission for both sides. They will tend to forget to change the Target objective from destroy to defend.
That and they will have US planes using the no parachute option to make the mission more frame rate friendly and then forget to change it when they have the Player flying those planes.
M4T is hosting all of Flying Nutcases old tutorials which were also another great mission building resource for many years.
