I can confirm that the Editor is not functioning as a cheat - all civs receive whatever changes made to non-unique planet structures.
But A+ for effort :P
I second this... Wait for Stardock to figure their s**t out for a bit.
Editor totally working. The values you edit ARE what is used to affect those tiles. So if it affects ALL CIVS, that is a programming decision by the developers. Use it or don't use it. There isn't some "other" value I can edit to provide that.
