Gruthkul's Pelt's "Your Spells are Disabled" mod disables Mercenary combat AI

When a merc has Gruthkul's Pelt equipped, they won't move or attack anything. They teleport when I go too far out of range but otherwise are completely stationary. I think it's because their AI is coded as a spell and is disabled by the "Your Spells are Disabled" mod.

The pelt worked fine for me, however a buddy DID have that same bug on one striker in particular.
We suspected it might be because said striker had dual strike of vulnerability, which may turn it into a spell.

Interesting, I tested it on Earthshaker and Kineticist, and it broke both of them
