not sure if this is gonna throw a spanner in the works, but i find that tugs take ships to any repair station, be it an MRS or a fortress. at the moment i can leave a few tugs in a system with a fort and take the MRS elsewhere but what will happen if tugs are docking?
Well, I didn't think of this particular situation. But something has to be done to the repair system.
In a game with a friend both of us had a MRS, but only he had tugs, I had none. Nevertheless, for some reason all his tugs pulled our sick ships not to his MRS (which was conveniently placed under a forcefield near the fighting, right behind the front) but to mine (which I had actually forgotten under a forcefield in the far end of the planet system), in the process insisting on running through a few enemy minefields en route. This was just so - stupid.
Why did the tugs consistently choose the most far-away MRS? When I turned off my MRS, they went to the other one, but as soon as I turned it back on, again they hauled their stuff as far away as possible.
I really believe that tugs should be closely related to their own MRS.
