The search function isn’t working for me at the moment, so apologies if this has been covered. Regarding timing for Autopilot Drone’s charge use - based on the order in which the player chooses to use dock/undock, or just the fact that the drone was undocked during the systems phase at some point? The drone docks and undocks at its initiative. Since Rigged Energy Cells just says “During the systems phase, if you are not docked...” I’m not sure on timing of the charge loss vs docking (or undocking) the ship.

EDIT: How I see it, at any point in systems if you are undocked (so, if you undock during, or dock during) you still lose the charge. So you could undock, lose a charge, next turn lose a charge and dock, then its an undock into explosion at end of activation on some third turn in the future.

I think the controlling player choses the Order in which He docks/undocks and Checks the drones Pilot ability.

So He can decide if He wants to lose It a Charge or not.

Yeah the controlling player gets to decide when resolving that ships Initiative step in the Systems Phase, he has 2 effects to resolve on that ship, the Rigged Energy Cells and Deploying. You can resolve them in either order as per the rules for the Ability Queue.
