i am not sure if theses are problems... but actually i think there are some little mistake in Irreversible's diff (or to say just make this mapset become perfect)
00:51:072 (1,2) - stack problem( this 2 notes are not in same position)
and there are also some same kinds of this problem(during kiai time i find a lot) , but the reason why i just mentionthat one cuz it was really obvious when i played this map
while in fact this kinds of problem doesnot affect much during playing. but i think it is better to change it
anyway congratz
