Fully compatible - however, when habitats spawn, including starborn ones, Guillis PM runs a set of script to add modifiers and a habitat designation based on the local planet, this will often end up with an additional designation being added, particularly to farming planets (so they will also gain the ability to have an astro mine, for example), which could push the starborn district out of view.

There are 2 solutions to this:

Use a UI mod that allows for a bigger planet view so you can see more than 4 districts, either "Bigger Planet View" or "UI Overhaul Dynamic" will work. Note that the Planetary Diversity Planet Viewer does not and is locked to 4.

A decision has been added that lets you remove Mining, energy research or farming designations as appropriate. Once you enact it your ability to build the erroneous district will go away.
