I have a bug where right after finishing Pine Island, whenever I try to go up at the four way intersection (with the jail on the left), it gives me a black screen. The music still plays, and I can access the menus, but there's nothing on screen. I had to reload from much earlier in the game and now have to play until that point again. How to I fix/avoid the glitch from happening if it happens again? I don't care about progressing if it's the end point of the build, I just want to be able to go back to earlier locations.
