I have researched the required technologies for xeno factories and xeno research laboratories some time ago, as well as Research Institutes now (upgrades xeno labs), but on my planets, i can only build "Research Laboratory" and "Basic Factory" (the starter versions of those buildings, 2 tech levels behind for labs, one for industry.)
Known issue? Am I missing something? Any suggestions (new game likely to fix it?) New buildings like the technological capital are showing up ok.
