End Game sequence winds up in infinite drum roll music after AddmusicK (not desired)

Hey y'all,

I am trying to make the final boss in a hack I'm making Lemmy instead of Bowser. I got the credits to roll, but instead of it playing the music I inserted into 1C, 1D, and 1F (the credit's music slots from Vanilla) it ends up in an infinite drum roll as the score appears on the screen before the credits. Then, during the credits, the custom music doesn't load, so the drum roll just loops. I can think of two possible issues: the Lemmy boss triggers that drum roll, then the game does not know what to load after that so it gets stuck OR there is something else amiss with the music.

Either way, instead of starting the music I have chosen, it gets stuck in that drum loop. Does anyone know a possible fix?

Best,
RT

I used the "Change Boss Sequence Levels" option in the overworld to change which level triggers the end sequence. It is the level which you enter, not the level that Lemmy is in.
