Planets can still be placed too close to each other, resulting in impossibility to change planets with orbital units/nukes
I thought I'd like to bring this up, as it is a rather irritating problem, that wrecks a lot of games. This usually happens when two planets are too close to each-other's orbital layer, and the orbital movement circle thingy is are no longer two circles connected together, but two separate arches. I hope that made sense. Nevertheless, this is already in the bug tracker, but I thought it would deserve some attention.
