SW: Lo Wang Rap does not play after beating the original campaign

After defeating the final boss and watching the end cutscene in Code of Honor, Lo Wang says "After all that work, Lo Wang feel like a song! Heh heh.". The game should then start playing the "Lo Wang Rap" song while looping through the credit textures on screen. However, the player is booted right back to the main menu with the main theme playing after Lo Wang says "After all that work, Lo Wang feel like a song! Heh heh" in VoidSW.

This happened with Interlopate SO on and off.
