This thread's purpose is to categorize various issues and provide potential suggestions, that said, it's kind of pointless to offer suggestions without a bug, balance, or compatibility issue. The mod author is currently working on another mod right now, after all!

1) As stated in another Discussion: Terraforming is broken with this mod. My suggestion is to incorporate the Real Space Terraforming mod. It would be phenomenally cool if, in order to terraform a uninhabitable planet you need to first build a colony on it... And then once the Situation is complete it removes the habitat flag and converts all buildings/districts into respective types.

2) Planetary Stations are insufferably weak. The costs of influence, 5000 minerals, and huge alloy upkeep is met by something that has -80% growth speed, no Features to make use of, and a Decision that I have never seen work to try to find Features. Put simply, the only planetary station that is justifiable are the Military and possibly Penal Stations. My suggestion is removing the decision to find new Features, making it so that any orbital deposit on the Celestial body gains a Planetary Modifier allowing this mod to gain Features matching the deposit (including special modifiers for Anomalies!), allow making Districts all the way up to the planet's size (with Alloy upkeep or something), and allow building Forge/Factory Urban Specialties. Without major buffs there really isn't any point in building Planetary Stations- they cost more than they produce in every single game I have played with them (I only build Military Stations now because of that!). They're neat, but that's all they are.

3) The update for new specializations for districts is broken. Any mod that adds Buildings or Specializations will not able to target this mod. I don't have any suggestion for how to fix this nor do I know if it's even possible to add compatibility based on how the mod's planetary stations work.
