Stellaris Update 4.0.22 Release Notes
Stellaris update 4.0.22 delivers major Wilderness empire changes, strategic resource balancing, fleet command limit increases, and extensive bug fixes.
The massive 4.0.22 update for Stellaris overhauls Wilderness empires, rebalances strategic resources and trade policies, adjusts fleet command limits, and implements hundreds of bug fixes.
Wilderness Empires and Economy
Wilderness empire jobs now automatically work without requiring biomass, utilizing primary species pops with fully usable customization sliders. Grown pops now spawn in default strata and jobs rather than remaining unemployed in parent strata. Planetary automation no longer keeps civilians around, and base command limits for fleets have been substantially increased.
Resource and Building Rebalancing
Arc Furnaces no longer drop in mineral output as alloy output rises. Strategic resource production from industrial jobs has been reduced, while refinery buildings and rural job extraction rates have been adjusted. Trade policies receive rebalancing across all major options like Wealth Creation and Consumer Benefits. Industrial sector features on relic worlds now grant +6 farming district capacity.
Policies, Traits, and Slaves
Technological Ascendancy now unlocks research policies to increase tech category draw weights, alongside new research restriction policies. Unemployed non-slaver guild slaves remain in the worker stratum without demoting to civilians, can auto-migrate without transit hubs, and do not trigger rising unemployment events. Trait modifiers for charismatic, repugnant, and organic organs receive adjustments.
Bug Fixes and Polish
Resolutions address issues with the Controlled Evolution achievement, Slaver Guilds constantly reassigning slaves, and biological ship roles. Science ships can no longer progress archaeological sites without a leader, and purging correctly disables regular pop upkeep. Numerous localization errors, tooltip miscalculations, and missing modifier bugs have also been corrected.
Why this patch matters
Update 4.0.22 brings sweeping systemic changes that redefine empire management, resource logistics, and slave mechanics across the board.
