Across several maps I seem to be triggering some sort of blindness bug. With the lighthouse it's the stairs, and with Camp Woodwind it seems to be with the barrier between the truck and the gate. When it happens it darkens my screen to the point I can no longer navigate, see objects, etc. I've taken some screenshots to showcase what I'm seeing and no it doesn't fix when I enter the van. It will fix when we leave the bugged map and then start a new contract. I don't need to leave the game.
