Well the Pave Penny itself is not a designator, it's a seeker, i.e. it's passive, doesn't emit laser energy for the bombs to use. If you use the A-10 Modern you can use LGBs. As far as the pod.. you can use the AN/A-173 or something like that, it's just the same. I mainly looked for it for the Tomcat, since end of use always used that in lieu of the older ones. I'd like to help right now but my mind is fried from trying to do other coding stuff, but one thing, you don't have to specify it on the Loadout.ini, it's just pylon counter, and it works for me, but try this code:
