I just finished Privateer 2, but missed a few of the cinematic missions over the course of the game. They just never showed up for me. I've read in a few places that it is possible to get these after the end of the game, but so far I have not been able to get any of the cinematic missions. I've tried going planet to planet a few times but to no avail. Am I missing something or do the cinematic missions become unavailable after the end?
