It's because they are shortcuts.

I'm currently trying to get back my Channel, i swear Youtube's automatic system for reviews is a piece of shit.
This is so annoying.

Hina Hirasaka
-Fixed error where Shinenzan EX gained meter on hit.

Battler Ushiromiya
-AI scaling.
-AI behavior changed.
-Some FX changes (Credits to PackmanMUGEN).
-Hitsounds of his Blue Truth changed, since it isn't a laser beam, now it uses his original hitsounds.
-His new jC is his old jB and vice-versa.
-Nerfed Elegant Blue Raid hitboxes, but now it has a small helper box to prevent whiff in close range.
-Damage values adjusted.
-Blue Truth startup reduced.
-More characters voicelines/special intro Vs. Female:
-Kirino Kousaka
-Hiro
-Hiro Two
-Etna
-Hina Hirasaka
-Shimo Hiraska
-Towa Yuhazaki
-Cirno
-Saki Mitonoya

After four attempts with pure Fighter Factory crashing, i will try to get to Noel NOL again.

-Fixed error where Issenkuosa didn't kill the enemy in her Yugizan/Retsugizan run, for example if you used Issenkuosa against Ichida's Adler with his Blitzgeist active, it will result in him succesfuly surviving Shimo's attacks instead of dying because the energy ball would save him.
-Fixed error where she still used Hina's code for special intros in turns mode, so she now will do her intro against her sister properly.
-Deleted Hina's sprites that were left in the sff.
-Deleted unused custom sprites. (group 190,2-4).

Known issues: She needs color separation like her big sister.

Update: They will not doing anything about my channel and it's gone, this is just unfair and shit. I have no words to express my anger right now, the account i used as my YT channel it was also for my personal entertainment and other things too.
Again they didn't told me wich video was specificaly "harmful".
I replied instantly their DM but they stopped contacting me after that.
