I was playing and just cleared the police station and headed outside.
Jet is flying over and the radio was talking and the game crashed. Got back in and trekked to the town and now it says I have to get outside but wont register I am out and continue the main mission.
I am playing on the PS4, solo (invite only).
Thanks for your time.
EDIT (Work Around):
did the mission with a friends world and it completed in mine as well.
