Geoschmo, yes please do set up DNM 1.70 for PBW. I have gotten no bug reports so far and haven't found any myself. So it seems to be stable. There is no update planned for some time.
Mylon, there is no ability that will produce supplies regardless of the suns.
Maintenance reduction would not be available to ships, only for bases.
Not sure what you mean with the typo for the prospector hull. I checked it and found no error. The 80% is for the combat disadvantage, the 90% is for maintenance reduction.
Jimbob, thanks for your input.
One problem that I see with strategic movement for bases is the Propulsion Expert advantage. Maximum movement for bases would be one. Of course that means two for prop. exp. Big advantage? y/n. Especially when base movement is easy to come by. Maybe the ruins tech solution would be good? This way you can't really plan on getting and using it (plus I'd love to add more ruins stuff

). Or just can the idea altother? Hmm, more pondering needed... sorry for rambling.
I sure wish that the emergency propulsion worked for vehicles with zero movement. That looked like a very promising solution. Oh, well.
