So it looks like the following will be required now to have a successful (containing all required commodities) economy of the refinery type:
- Only build two types of structure, colony ports(may need 2 t1 if starting at t1 primary) and refinery hubs.
- All structures must be built on a rocky body with nothing on it re: biologicals, volcanic activity, etc.
- Nothing with a replaceable colony econ can ever be built in the system anywhere else, including the system primary. This means any system with a non-rocky primary slot cannot ever have a fully functional refinery econ.
- Make hubs override all weak link influence (solves #1)
- Make hubs override all planetary influence (solves #2 and #3)
- Allow players to pick an econ type for orbitals (solves all 3)
