So I just finish the mission where Trevor and Franklin steal a Z type or whatever it's called where you use a helicopter to track it then take it to the airport. I think I also started working for Solomon and did his first mission with the helicopter.
After that and maybe another mission or two, there's no main story missions showing up and no way to progress it. Am I missing something or did the game bug out? There are a bunch of freaks and geeks missions for each of them but I don't really want to do those if I don't have to. I tried calling a bunch of people on different character but that didn't help either.
