alright, so ive been working on a friday night funkin' mod for about two days now. ive imported camellia's "ghost" and i made a banging beat map for it. problem is, when i saved the .json file to the actual game, it seems to crash

ive made the song work just fine, but when i click save on the debug menu, it gives me a .json file. so i save the file and overwrite the old ones, i click enter to test the new song out, and it crashes. what am i doing wrong?
