Ok, when I copied the Advanced DB without any changes, no air units may be placed
When I copied the Enhanced DB without any changes, no air or orbital units may be placed
When I tried my database with a new unit, no air units are placeable. I tried playing it and discovered that my new unit could not be produced in a city. I went back into the DB editor and added my new unit as transportable by the city. I started a new game and all the air and orbital units may now be placed ??? If I go back into the DB Editor, the terrain placement blocks are still grayed out and inaccessible. If I save the DB and start a new game, no air or orbital units may be placed.
