Hi I have this game called "REBEL RAIDERS OPERATION NIGHTHAWK" and I cannot go any further in the game because it says that challenge 2 is locked please complete challenge 3 to unlock. So I completed challenge 3 and challenge 2 still says locked. The game even says "completed" on challenge 3. It says challenge 4 is not available so what is the problem? I have tried completing challenge 3 again (3 times) but it still says locked. Is it a glitch? Should a start over from a new game and get to that mission again and see if it still does it?
