I played the song great nano desu and i noticed that on my third attempt at the song, a duplicate of one of my scores has been made, which was my first attempt if I remember correctly. Idk how it got there, but it's the same combo and score, as well as the same number of of each type of hit. I only recall playing this song 3 times.
Edit: I JUST noticed the same thing for the other dificulties of this song. As well as a couple of other songs. Idk if this was because of a certain time period or whatever. As for another song, I suppose because maybe I played it twice but it has 2 copies of 2 different scores.
