c[confirmed]Damage redirection + Cho-Manno style crits

[Nexhro]

Describe the Bug:
When Cho-Manno, Revolutionary is equipped with Pariah's Shield, damage redirected to Cho-Manno is prevented correctly.
1) If Cho-Manno is enchanted by Pariah, though, the damage dealt to it is not prevented.

2) Dawn Elemental takes damage redirected to it by Pariah's Shield and/or Pariah.

3) Combat damage redirected to Seraph of the Sword is not prevented, when it's eqipped with Pariah's Shield and/or enchanted by Pariah.

Which card did behave improperly ?
Cho-Manno, Revolutionary or Pariah, Dawn Elemental, Seraph of the Sword

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
JOU v1, duel

What exactly should be the correct behavior/interaction ?
If Cho-Manno is enchanted by Pariah, damage dealt to it is prevented.

Damage redirected to Dawn Elemental by Pariah's Shield and/or Pariah is prevented.

Combat damage redirected to Seraph of the Sword by Pariah's Shield and/or Pariah is prevented.

Are any other cards possibly affected by this bug ?
Possibly also occurs when other means of redirecting damage are used. Some examples would be Shaman en-Kor, Nova Pentacle, General's Regalia, Kor Dirge, Captain's Maneuver or Harm's Way.

Actually didn't work for me with Cho-Manno equiped w/ Pariah's Shield (died from 2 Black Vise s redirected).

In the provided savegame, I equipped Cho-Manno with Shield and damage dealt by Manabarbs was correctly redirected and prevented. Tapping all flying creatures I controlled via debug command resulted in the AI attacking with all its flying creatures and again damage was redirected by Shield and prevented as intended. So this might have to do with the fact that Black Vise is coded in ASM (which would be weird since Manabarbs is most likely in ASM, too) or with artifact sources in general?

Edit: Gave AI 2 Black Vises via F2 and F3, respectively, in the savegame and damage was prevented. So maybe the savegame is messed?

Tried a few more times, and it sometimes works and sometimes doesn't. If you load your savegame, proceed to your main phase, equip Cho-Manno with the unequipped Pariah's Shield, debug 2 Black Vise into play for AI and then just keep hitting done, damage isn't prevented. I've also killed Cho-Manno with a Lightning Bolt, although that usually doesn't work. There must be something going on I'm not seeing.
