The mod is based on Lili's alternate outfit (3rd).
Selecting the mod at the same time as the alternate outfit will make the game crash (one on P1 and the other on P2).
That's why the mod is named 03 and should be use instead of her alternate outfit.
(If you don't use the alternate outfit, you can rename the mod at will.)
