The timing for the map is somewhat wrong
BPM should be 160 flat, no decimals
For the offset I suggest 9860, as this is where the music starts.
Once you apply this, you will have to resnap every note to the correct beat + you need to redo the sliderends
Mapset Verifier can help you identify missplaced notes & sliderends
03:47:900 - add a note here?
In reference to 03:46:550 (1884,1885,1886) - you do have the song supporting a note there, so why not add one?
