My beatmap started off as 96 bmp. In the middle of the map, I used an uninherited point for a bmp change because I wanted a faster slider (changed it to 215)(learned that you should use an inherited one, this is my first map). In the process, it basically shortened all my placed notes for some reason. I think this is due to the 'Moved already placed notes when changing the offset/bpm' setting. However, I have no idea how to change it back and I've saved the map so I cant undo it. I've spent quite long on this map, about half way through. Can anyone help?
