I used "mode=o status=r"then it shows 57923 lol.And I'll check these maps whenever I have time.
In fact, I downloaded these maps through osu!api. And some sets are CORRUPTED.(I had found 2 sets have duplicated diffs,for their filename is ACTUALLY NOT SAME) So I have to make sure how many sets have this problem.
NEW NOTE:By checking sets 1-1005 ,the number of maps is 57914 now ,still 2 duplicate diffs to FIND OUT.
