Hive World Origin
This mods adds a new origin for Hive Minds, "Living Planet", which lets you start on a size-21 Hive World. it also gives your species Hive World Preference and a 20% head-start on the Terrestrial Sculpting technology.
Note: there is a graphical bug where, for the first month or so, the planet appears to have no room for districts; simply click off the planet and back on after the first month and it should be fixed.
Should be compatible with everything; please leave feedback and suggestions!
