Op-fire at hidden units

[Von Earlmann]

Had this happen in recent turn of EF. An enemy armor unit moved into a hex with no other units visible. My armor op-fired twice at an unseen infantry unit with no effect. Needless to say when the enemy armor fired it was very effective and the unseen unit remained hidden during the entire exchange. I know during regular play units cannot fire at empty hexes and unseen units. So, why can they fire at unseen units during op-fire thus wasting the intended shot? Hopefully this is a glitch that can be fixed as there is the potential for some gamey tactics here. Nothing like moving armor into a hex and having an unseen infantry take the shots and then demolishing the opposing units. I don't recall this ever happening in previous versions.
