So, whenever I exit the game, I quicksave so that I can go back to the place when I load the game again. But, whenever I load a quicksave, first off, I constantly hear an engine-like noise in the distance, no matter where I am. But mainly, whenever I drive to a new area, it deletes everything in that place and replaces it with the type of area I quicksaved at.

For example, if I quicksave in a gas station, and then load that save and continue moving onwards, whenever I come across a new area, such as a highway checkpoint, if I get to a certain point, it will delete the checkpoint and everything around it, and replace it with a gas station, like the one where I saved and loaded the game.

Is there a way to fix this, so that I can quickload back in and continue going along like normal, or will I just have to start again with a new vehicle every time I exit the game?
