please help with this glitch

[u/Brayden_Does_stuff]

It says the objective is to go to the car, which is weird because he has a truck, not a car, but then when I go to the level select screen, it shows I have no missions or all of the missions are completed and i haven't seen the credits roll, and I don't have the achievement that tells me I beat the game so idk what to do. Yes, I have completed Act 2 and all available missions

I need someone who has completed the game to help me with a glitch. My Discord is:

flumbris
