Hey, first-time poster.
I got very tired of my exploration ships being shot down when they encounter NPR's, so I designed a two-stage delivery system for geosurvey buoys to check out promising planets in the inner system. It's the first missile system I've built, so be gentle.
The trouble is, I cannot get the darn things to launch! Someone mentioned above that drones were messed up, but it's been a few versions since then, so I assume they're fixed.
I've been assuming that you don't need missile fire control to hit a planet, but just in case I've tried it both ways. In every case, when I "launch missiles at" the planet (or a waypoint on top of the planet), the ship flies directly to the planet, then apparently does nothing. I lose a drone from the ship's inventory, but no geosurvey data ever comes back.
(What sort of sensor do you put on a guided missile, by the way? If you want it to hit a possibly uninhabited planet, that is! Active sensor?)
EDIT: Curiouser and curiouser. In my latest attempt, the ship flew directly to the planet, then launched the drone - at the sun. I have tried this with several different planets - the drone always launches at the sun. Very weird. (The version had an active sensor on it, maybe that's it?)
