FM2 file begins from a savestate

Taking damage on the same frame as killing a boss results in $75 being set to 4, where normally $75 is always 0. This can occasionally prevent speed values from being added to enemy projectile positions, illustrated here with the bullet-boost leaving 4-1A causing a desync (though other bullets in the level are affected too).
