Bad news:
Started a quick test game (large quadrant, few AI, no events etc) .. after 20 turns, those 2 (!) AIs
again have "research compounds" with 1 spaceyard build and 4 empty facility slots ... and even an empty build queue !
And now don't tell me they're both building scouts all day long because they're feeling so lonely in that large quadrant
Savegame attached .. in case someones wants to have a look .. master-password is "master", again ..
