I've read elsewhere that a planet is required to be upgraded to Enigmatic before I can build Dark Energy Pylons, but for me, I can't build any as my UI says that they need a planetary processor (playing Machine Empire).

Then there are all the other buildings which are now locked out, like Planetary Supercomputer, Negative-Mass producing buildings, etc, that required planetary capital buildings above a certain level.

Is that a bug, or something weird with my mods? Seems like most of the other enigmatic buildings are working fine, just... not the ones I need to build dark energy, so... running at quite a deficit on my planet...
