Treaty level bug?

[Puke]

I managed to get two AI races (one neutral, one real) to agree to subjugation treaties with me even though I had never seen their systems before. I think the suckeers opened a warp point from somewhere and ran into one of my fleets. I would have SUPPOSED that subjugation or protectorate would give you access to things like blueprints, system maps, telemetry.. all the stuff you get from a partnership.

I had never really noticed it before since I had never gotten someone into one of those treaties that I didnt already have maps for - but when they agreed to the treaty (and i started recieving tarrifs from them) I never saw where their systems connected.

Is this a bug or is it intentional?
