ench_mod_LegendaryArmor_Chameleon uses the
ChameleonEffectArmorMod effect, even though it was only meant to be used by the Stealth Boy Power Armor modification, as evidenced by the script name. As a result, when multiple Chameleon pieces are worn, the visuals and sounds (which shouldn't even be present in the first place) become very disruptive to gameplay due to stacking. To fix this, a new chameleon effect without script data will need to be created and plugged into the legendary effect.
