This is not a bug as such, but almost, and imo needs to be fixed. It’s about the construction material requirements for planetary projects and POPI. Some planetary projects like the warehouse, and the population infrastructure, require MCG to be built, and it’s the same cost on every planet, no matter whether it is rocky or gas, and no matter gravity, pressure or temperature. Imo these costs should follow the same pattern as for the base building. On an MCG+SEA planet one should require MCG+SEA, and not just MCG; on an AEF+INS gas giant one should require AEF+INS instead of MCG, etc. Otherwise it’s not flavorful and immersive.
