I have an ability that is shared (used) with two units. The ability shows fine on the command card on one of the units and on the other, the ability shows as greyed out with an incorrect requirement "Not being attacked". I have verified that I am using the same ability and buttons between both units. (The ability itself only has one unrelated requirement that has the Show flag -- under (Basic) Can Be Suppressed turned off)
What could be causing this kind of behavior? I'm a bit stumped.
