Let me clarify at least Wafu's suggestion with the red color in Japanese and English so that mappers and he can understand what I mean.
This is probably the first time for me to see the edge case which timing stuff caused lol
01:35:365 (1) - 赤線が01:35:810 - にもあるから、AiModが01:35:800 - (前の赤線が元になってるタイミング)と01:35:810 - 両方が正しいタイミングだって判断しちゃってる。この場合、実際に正しいタイミングがある位置は後者の01:35:810 - だから、そっちに合わせないとUnspanned ObjectでUnankableになっちゃう。ほか難易度も同じく!
Since there is the red line at 01:35:810 - too, AiMod mis-judges that both 01:35:800 - (based on the previous red line) and 01:35:810 - are correct. This case, the actual correct one is definitely the latter one 01:35:810 - , so the current slider with the end on 01:35:800 - is considered as the unsnapped object which is one of reasons for disqualification. The same goes for other difficulties!
