02:14:072 - I would replace the ending triplet with a short slider like this https://prnt.sc/1is1rxp
00:50:693 - I would move the 2, 3 and 4 so they stay together but are under the 1 like this https://prnt.sc/1irzauc
I understand that you want them to be stacked, but here the cursor stays too long in the same location
I would remove the kiai from 02:25:539 to 03:08:795 because after listening to a long drop you get used to it and it doesn't sound so "epic" anymore. I would then remove all small kiai gaps, so the whole song has 2 big kiai sections like this https://prnt.sc/1irk2qq
This way you solve the first two AiMod issues, and for the last one, yeah, you don't need 2 diffs, it's certainly a bug.
