Weird, I know all civs since turn 159 and I did nothing to achieve that.. Either Beam or someone else traded all contacts around.
Of course, techs spread around in the process, which leaves me as the most backwards civ on the planet.
OTOH the contacts are just fine with respect to the nearby TGL. The raid
will be delayed a bit since I dont have enough money yet to do all the upgrades (spent to much on printing press research which now appears to be worthless).
