- ships with hangar bay can haul vehicles.
- ships with docking bay can haul ships.
- ships can haul raw materials according to their weight/volume capacity
- ships can have a docking bay, hangar bay, both or neither.
What happened with making it so you could carry ships and vehicles in any of the two with the difference that hangar bays wouldn't be able to deploy ships in space?
That isn't the case and I don't know of anyone working on it. I was under the impression it wasn't even solidly decided on by the rules/implementation teams, but was just being tossed about in Suggestions.
I believe the last thought on the matter was to have Cargo and Docking bays. Cargo bays being able to hold anything and to be able to transfer to and from the docking bay but not able to launch ships/vehicles. Docking bays able to hold ships and vehicles.
Keir just posted something similar in the J-type thread in one of the Suggestions forums. Still haven't seen anything official on it, but I assume it'll be announced.
