Oddly, the bottom custom system is not allowed to be edited, the odd thing, is it prevents any system from being used or made, attempting to edit the null system opens the editor proper, but I can't save that either. Anyone know the cause of this? I have reinstalled the game several times, along with testing the game with and without mods.
That's rather strange. You can probably fix this by clearing all of the user data though. That is, delete the following directory: Windows: %LOCALAPPDATA%\Uber Entertainment\Planetary Annihilation On a typical install %LOCALAPPDATA% will be C:\Users\<username>\AppData\Local OSX: ~/Library/Application Support/Uber Entertainment/Planetary Annihilation Linux: ~/.local/Uber Entertainment/Planetary Annihilation Or to be on the safe side, rename that directory first. That way you can rename it back if it didn't work. Note that this will delete ALL user data, which means settings, Galactic Wars, mods, etc..
