Spies help in planatary invasion!? ...
I still think that tactic/exploit should have alignment effects, even for civs with a formal alignment (applied Xeno Ethics). Sending hordes of troops to exterminate civilians is bad enough; sending spies to wreck and/or poison the local food system, well, that's just really evil...
One wierd thing about the starbase repair module, it's there in the .xml files and appears in the tech tree, but it doesn't show up in the module list even if you mod it into the game with no requires. Looks like it was supposed to work, but doesn't because they never got around to fixing it. Too bad, that would have been a useful addition.
I'd have built some military bases just to have those Repair System modules working in important spots that were far from my systems. Seems like they'd be a real help with things like clearning out enemy hulls before sending in troops or defending a beachhead system against a strong opponent.
