No AI Habitats
The AI will no longer build habitats, because habitat spam is (a) stupid and (b) creates wayyy too much lag and tedium in managing conquered planets. EXCEPTION: Void Dwellers can still build habitats in their guaranteed ideal systems, but shouldn’t do so anywhere else.
Consider only using this mod in games where you also are running mostly habitat-less so as to keep some degree of balance and hew to a headcanon of "a space station cannot house as many citizens as an entire planet."
Works with Stellaris v4.3 and v4.2 because habitats were more or less unchanged between updates. This mod overwrites the vanilla file common/megastructures/habitats.txt, so it is not compatible with achievements or any other mod that edits that file.
