This seems to be gone once the game is unpaused. I would assume that the slider was unset to export whilst the game was paused and thus didn't update. Fixed the code to update it every-time.

While it's been a bit since I posted this, so my memory is a bit hazy, I'm almost certain that this was persisting even while unpaused at the time. I only noticed this issue because my vehicles were acting abnormal. If I run into it again, I'll make sure to post here.
