this is a recently ranked Easy diff, every note is placed with distance snap on (http://osu.ppy.sh/s/52709)
but AImod still says it has 38 spacing warnings, in fact every (2)-(3) and (3)-(4) in a combo is a spacing warning
this map is not the only example, it happens with every map
this is a real problem, it used to be able to detect spacing problems in Easy/Normal stuff, now it can't
