Right on Frostion. yea I erased a image and then put one dot on it. That didn't work. Then I found an invisible one on one of Rolfs maps but it had the same result.
On the global map UK Pacific's unit's all turn British after they're placed, except for their infrastructure. I have a 2-hit unit that requires other units to place it and repair it. So UKP couldn't do it because it wasn't it's own unit.
Zim Zero said invisible units aren't meant to be played, just sense conditions. So I guess it didn't like the fact it had repair and placement abilities. Anyway I switched over and gave everybody their own production Frontier. It solved the repair issue but not placement so I just made it placeable without requiring any units. It'll have to be player enforced. Not a huge deal as this unit will rarely be purchased anyway.
I'm gonna test your image as well as I still don't fully grasp what they can and can't do.
