Little bug in my game; for some reason, vehicles with a flame pipe (not the Magnum Opus), such as the Flamergamer, Charbone, or Fire Raider have weirdly behaving flames. When accelerating in one of these vehicles, the flames will start to drift forward (through the body of the vehicle), rather than backwards (as they should). When reversing, the opposite takes place, and they shoot out. The flame pipe still functions as usual, but it'd be nice to fix this graphical issue.

Only similar thing I could find online:

Note: I *DO* have the legitimate, purchased GOG version
