Just want to put out another bug for you:
The salvaging drones mechanic can cause you to go above your drone bay's limit.
Hello, thank you for your feedback, this is intentional. Players can build a lot of drones in their planets and then recall them to their Cruiser and overflow the capacity as well. They just won't be able to produce more drones from their Cruiser until it is below that limit.
Ah, okay then. Interesting mechanic, although it seems like it would be easy to abuse and spam drones in attacks.
