I have made Concord Cannon's target filters to only require visible, and it shows liberators are allowed to attack both air and ground units in the game properly.
However, when I attempt to use it to attack air units within the area in AG mode, I receive a Validator result failure message from validator "Liberators AG targets".
I tried modifying the comparison of the validator from "greater than" to other options, but it results in Liberators being allowed to attack units outside the area like a siege tank if included equal, or not being allowed to attack at all if smaller only.
Can you please advise me on how to solve this problem? What is this validator actually comparing? Thank you.
