Problem Details:
The star rating calculation goes wrong when timing points in *.osu file is not sorted. Especially, the SR goes extremely absurd when the unsorted timing points involve speed-changing ones. What's more, the error can be repeated easily. I guess this is due to the lack of robustness in CTB SR calculation.
However, if people save their bugged maps in osu editor, the star ratings will become normal.
This happens to both converted maps and CTB-only maps.
