anti-planet drone woes

[Swarm]

My first post

I've been trying to make some use of drones in a PBEM game (v1.91).

Anti-ship drones are fine, but I can't persuade a carrier to launch anti-planet drones in the simulator. (And I'm loathe to try them out in the field until I know they will work)

I've tried various alternatives -

• drone carrier with/without weapons.
• design type "Drone Carrier" or not.
• ship (& fleet) strategies optimal, max range, don't get hurt etc.
• drone loads of anti-planet, anti-ship and mixed loads.
• I've tried various strategies for the drones themselves too.

The only way I can trigger a launch is to define the drones as anti-ship (but with anti-planet warhead and a strategy which prioritises planets), and ensure there is a ship or base in the simulation as well as the planet.

I have had zero success in getting them to launch against a lone planet during combat.

What am I missing?

If someone could confirm that they have succeeded in this, I'd appreciate it. Especially if they could tell me the strategies and drone design.
