Broken King Boo fight after resetting into casino

[QbeRoot]

Resetting into the Sirena 5 casino (either with Z or C-down + X) after defeating King Boo without grabbing his Shine causes weird side effects the next time the fight area is entered: King Boo immediately makes his “canceled cycle” sound while the center of the roulette is still above him, said center stops in the air, and the fight starts like that. In that state, resetting again before King Boo shows up will make the same thing happen next time.

This doesn’t happen upon loading into Sirena 5 with C-down + Z at the end of the fight, or if King Boo’s Shine has already been collected.

This is probably related to #2 and the Manta glitch with some states or flags not resetting properly when reloading a level.

Might also be that these things can happen in stages which have a special behaviour defined in the dol rather than the scene itself. (Rollercoaster, Manta, Boo/Slots).
