Grant Buff: Direwolves bug

I have enchanted an artifact with the Grant Buff:Direwolves ability, but as far as I can tell it never does anything. I certainly never see any messages about Direwolves attacking like I have seen when the spell is used at other times. Playing in iOS with version 1.3.0.

Is the ability called Wolf Army? And if so, do any of your creatures start the battle with a buff called “Dire Wolves”?

The ability listed on the artifact is Grant Buff: Direwolves, and I believe the material I used to grant the ability was a Greater Inscription of Direwolves.

None of my creatures start battles with the Direwolves buff.

Found the problem - I’ll get this fixed ASAP. Thanks!
