Artillery Ballista, Eroding Chains, Armour Expolosion, Scavenged Plating

I'm not sure there is a bug here, but I just unlocked the Artillery Ballista skill and was hopeful to use it with the new Eroding Chains notable passive in order to trigger the Armour Explosion support gem and the Scavenged Plating Spirit Gem.

These interactions do not work at all. Artillery Ballista seems to never trigger Armour Explosion, nor Scavenged Plating when it breaks armour. It does not matter whether the ballista is breaking armour from Eroding Chains or from the Armour Break support gem either.

Really disappointing honestly.
