cda9440a296304bd710c1787436ea1a948f6c999 inadvertently fixes this in the
most frequent case by inverting the `TickDistanceMultiplier` from being
not-1 to 1 on beatmap versions above v8.
This can still potentially go wrong if a beatmap from a version below v8
is edited, because upon save it will be reencoded at the latest version,
meaning that the multiplier will change from not-1 to 1 - but this can
be handled separately.
