Additional context:
Is there a way to fix it? I know that this is no ace problem, but problem specific to the mutant's mod. Maybe override these values, by editing these problematic values

No, it's at least partially ACE problem.

ACE3/addons/medical_engine/functions/fnc_getHitpointArmor.sqf

Line 47 in 4fb9da7

_unit setVariable [_var, [_rags, _armor, _armorScaled]];

We should be checking if _armor is 0.

Might be even safer fixing this instead:

ACE3/addons/medical_engine/functions/fnc_getItemArmor.sqf

Line 66 in 4fb9da7

_return = [_armor, _armorScaled];

We should make sure that is can't return 0. Minimum armor is 1.

Hitpoint armor should be armor max 1, item armor should be armor max 0 because an item can not cover a hitpoint
