I think this bug is pretty much related to this one : t/216456 because they can be replicated with almost the same steps
1. Go to editor
2. Find a song that has different BPM's at the start and the ending ( this one for example: https://osu.ppy.sh/b/178645 )
3. Go to timing
4. Skip around the ending of the song (around 10-15 seconds before it ends) and wait till it ends
5. Press play and the BPM won't change ( the BPM tick sounds don't change as well)
