>>28109717Bumping my question because I still have no clue what's going on
>>28112888I removed the extra comma but it still crashed when I added Sylveon. Then I removed Sylveon but it still crashed without the extra cromma. Then I added the extra comma again and it didn't crash.
It turns out I actually needed to add 2 commas between happinessnight and sylveon to make the game not error upon bootup. I initated the evolution for Eevee into Sylveon and I think this only happened because I don't have a sprite for sylveon in the game yet.
