Q. Does anything in the current rules or errata - and yes, i've looked for it, though possibly not deep enough - prevent me from "stacking" naval repair facilities?
A simple example would be:
- Warship carries (6) Station 1-6 in six naval repair facilities
- Stations 1-6 carry (36) Stations 7-42 in its each six own naval repair facilities
- Stations 7-42 carry (216) Stations 43-258 in its each six own naval repair facilities
- Stations 43-258 carry (1296) Stations 259-1554 in its each six own naval repair facilities
- Stations 259-1554 carry (7776) Stations 1555-9330 in its each six own naval repair facilities
- Stations 1555-9330 carry (46656) Stations 9331-55986 in its each six own naval repair facilities
etc
At that point we'd be at a possible maximum of somewhere around 140 gigatons of mass already, and going a couple levels further would put us straight into Death Star territory.
The problem already exists with single repair bays per space unit (and thus can't be resolved by e.g. "blind faces" towards the carrier unit), as that would allow "chaining" them instead. The whole thing obviously has boundless other implications, including
this.
