Artanis Unbound Fanatics Not Spawning

Artanis’ Unbound Fanatics are extremely picky about whether they spawn or not. They will not spawn if the orbital strike is called down on a building unless it just clips the building with the edge of the orbital strike, it will only sometimes spawn a unit if the orbital strike is called on top of enemy units, it will never spawn if the orbital strike is called on a friendly unit (including other unbound fanatics), and it will never spawn if it is called down on the edge of your vision radius.
