Fork of https://mods.factorio.com/mod/Construction_Droneslk which is a fork of https://mods.factorio.com/mod/Construction_Drones.

Changes: * Drone speed halved. * Drone recipe more expensive(Space Exploration mod is required). * Players starts with only a single drone instead of 10. * Drones will no longer attempt to deconstruct factory buildings to avoid bugged interaction with Factorissimo mod(item duplication bug).
