Shattering Impact/Rending

Shattering Impact is no longer working as it was prior to 1.07.
Prior to the most recent patch my Grenadier gauntlet “Shattering impact +3 Rending(Armored Enemies)” would make it so each grenade I shot did slightly more damage to the big armored guys in Psykhanium. After 1.07 it no longer increases the damage at all for any attack.
