For some reasons, my drones in some places arent delivering, even though they have the material required and said material is needed at a depot; they're not going.
I have a long range drone depot within my main base's logistics network, fully stocked with drones. There are storage chests with chemical plants which should be accessible to the logistics drones and the long range drone depot. After activating editor mode, it looks like the drone launched without actually taking on any cargo.
