② Balance
• Wilderness Empires that finish the Domination Tradition Tree now have access to the Hegemony Federation Type

• Idle gestalt drones now demote much faster.
• Colony Auto-Designation no longer thinks that job producing buildings like Temples are 100x as awesome as it should consider them.
• Adopting Genesis Guides mid game will no longer prevent you from colonizing planets until you researched any new ship tech.

• The Control Fragment now waits 2 decades before getting upset about your borders. Expand away!
• Fallen Empire biological ships now equip the reactors of one size category larger, this also applies to Cosmogenesis biological ships.

(The Lathe had a "stable state" hack that stopped the purge below 40 pops to prevent it from decolonizing before - this has been removed as it should no longer be necessary. Burn those pops if you want science.)
