I left the game on for multiple hours to let the Legion try to make some progress, and when I came down on Haven (which had most of its facilities destroyed) there were no new Imp Hives. Instead, all the spots were either vacant or owned by non-allied structures.
Clearly something isn't working right. The Imp Hives are a big part of allowing the Legion to maintain control of a planet.
I'm playing on the Switch version.
