CS06_BossIntro.BadelineFloat causes an NPE

### My mods and Everest install are up to date

Yes

### I have recreated the bug with only Everest OR a minimum number of mods enabled

Yes

### Describe the bug

In vanilla reflection [boss-00], if you touch the CS06_BossIntro cutscene (without skipping it), then touch the FinalBoss, read the dialogues normally. After Madeline says "We need to move past this", the game crashes.

why: FinalBoss.OnPlayer causes its NormalSprite = null, while CS06_BossIntro.BadelineFloat accesses this field without nullity check
