I have a resupply base stationed on top of a jump point with around 50% fuel and 50% MSP. (commercial space station, marked as resupply ship and tanker in design, zero minimum fuel, zero minimum supplies)
I have a fleet of supply ships with 100% fuel and MSP. (commercial ship, marked as resupply ship and tanker in design, zero minimum supplies)
Both designs have cargo shuttles and refueling systems.
In the naval org menu, I can order the resupply ships to "refuel from own tankers" and they will transfer fuel to the base (in fact they will fuel the base beyond 100%, I'm guessing it's a bug, but I'm using Auroramod).
However, after I give a "resupply from own supply ships" order, the fleet completes the order in 10 seconds, says the order is complete, but no MSP is transferred. Merging the ships and base into one fleet, setting the ships to resupply own fleet, setting the base to not resupply, and increasing the base's resupply priority also does not transfer any MSP.
How can I transfer MSP from my ships to my base and is there a way to avoid having them refuel the base beyond 100%?
Alternatively, is there some easier way to maintain a station not orbiting a body? I've been using this resupply base to maintain a static weapons platforms to defend this jump point from hostile aliens. The maintenance modules have been drawing from the base's MSP storage, which is why I need to top it off.
