Stellaris Update 4.0.23 Adjusts Ion Cannons and Fixes Job Assignment

Stellaris update 4.0.23 brings power output buffs to Ion Cannons, fixes auto-modding trait scaling, and addresses widespread job assignment bugs across planets.

The latest Stellaris update focuses on economy and combat fixes, adjusting Ion Cannon reactors and resolving job assignment errors for planetary populations.

Military and Balance Adjustments

Ion Cannon reactors now feature increased power output, making auto-designed variants less likely to run out of energy for their main armaments. Additionally, capturing Tiyanki using a Gravity Snare no longer angers the galactic community, treating the action as placing them in a protected enclosure.

Economy and Job Fixes

Auto-modding traits now scale to 100 percent efficiency even when pop groups are assigned to multiple jobs. The patch fixes job assignment issues that previously left planetary jobs unfilled, resolves a bug where Necrophage secondary species refused worker jobs at game start, and stops Agrarian Villages from disappearing on wet worlds for non-angler empires.

Why this patch matters

Update 4.0.23 smooths out persistent economic bugs and balances specific military hardware, laying groundwork for future expansions.
