- If the storyboard ends after the beatmap, call updateCompletionState as if the score processor has completed at that time. (completionProgressDelegate is null here since earlier when the score processor actually completed, updateCompletionState returned after showing the skip overlay.)
- If the storyboard ends before the beatmap does, updateCompletionState simply returns and waits until the score processor is completed.
- If the storyboard and beatmap end at the exact same time, make sure updateCompletionState() is called only once by the score processor completion.
