SCI: Add a workaround for bug #3568452 - "SCI: QFG1VGA - Path finding bug in the forest"
This workaround has been added for now to stop the game from freezing.
A more correct solution would be to match our pathfinding algorithm
to what SSCI is doing, but with this workaround we can stop the more
immediate problem (game freezing) now.
