So i recently started mapping, but my timing is off, what i mean is that i time the songs correctly on my computer, then my friend tests it and finds out that the circles arent timed well at all. and im 100% sure its not me being off with time cause my friend send the edited version of my map to me and said he placed all the circles on the blue and white ticks, then i looked at it in the editor, and they werent even close to the blue and the white, can someone please help me
