The new armor sets aquired from the Master Grasp of Averice Dungeon have an extra mod slot that allows Seasonal Aritifact Mods to be placed in them, however, none of the chest peices for the 3 classes are showing the avaliable mods in the drop down menu for that new slot. In the traditional Mod slots, the Artifact mods *are* shown and can be equipped, but not in the new slot. The rest of the armor peices are all working fine, it is just the chest peices on all 3 classes. To reproduce this bug: simply make sure your characters' seasonal artifacts have an Artifact Mod selected that can be equipted in the chest armor (i.e. Fire & Ice), you have a chest peice with the Artifice Armor attribute, and try to equip the mod in the extra slot. They will not be shown as an option in the drop down menu.
