Immobile units turning

Kinda a dumb problem, but I can't get units (or buildings) with 0 Movement speed to turn when they fire. The closest thing I've come up with is setting Movement to 1, but I want to do this with immobile units.

Any idea on what makes immobile buildings (tidal guardians I guess) turn when they fire?

try the Root (Ancient protector) ability.

Units like the Ancient Protector and Tidal Guardians have a bone in them called "Turret" when applied to a unit that doesn't have a moment speed, the Turret bone faces the target.

if you use the OLD Ancient Protector Root ability, then it turns the whole building to face the unit, otherwise it still won't work.

Normal root ability works fine.

ye, normal root ability is ok, i have seen this in few maps
