ElfNeedsFood said: Something is off with the oil prices for the headquarters... At least at levels 3 and 4, you cannot store enough oil to perform the upgrade so you have to use diamonds only. Is that by design?
ElfNeedsFood said: Yes, the land is true. Since level 4 I have had a way to build enough buildings to store the oil necessary to upgrade. I'd almost need to replay to 100% know if there is a possible path for using oil to upgrade L3 and L4.
