Good to hear you managed to keep your old saves and can continue where you left off.
Which type of housing are you having problems with? If it is the Apartments that are doing it and you have no way of correcting the negative by building other housing near it, then destroy it and make sure you build something larger or upgrade an existing Habitat or Skyscraper that can compensate. Remove the negatives as much as possible and overcome the native adversaries in the process.
Seeing as we have sand worms and we are set only a few hundred years or so in the future, perhaps they are predecessors of Shai-Hulud? Perhaps this planet will be later known as the desert planet Arrakis or Dune? Especially, if they allow us to go find all the nests and kill the native wildlife off except for the worms of course. Maybe quori spice evolves and is used by the Sisterhood of the Bene Gesserit in an attempt to find the kwisatz haderach and also by the spacing guild to fold space? One can only imagine.
