[2022] button to build engineer and investor residences missing

@kaosink1965 Hey there! I am sorry to hear that you are missing the button to build engineer and investor residences. Do you have artisan residences build to be able to upgrade to engineer? Are you able to provide me with an image showing that you are unable to build engineer and investor residences to help look into this for you? Also, please try to verify your game files to test if that helps as well!
