Stellaris Update 4.0.10 Refines UI, Economy, and Automatic Resettlement

Stellaris patch 4.0.10 fixes issues in BioGenesis and version 4.0, introducing major upgrades to automatic resettlement efficiency, pop group merging, and planet UI layouts.

Paradox Interactive has released Stellaris update 4.0.10, addressing balance issues, user interface glitches, and out-of-sync errors. The patch is available now on Steam, with GOG and MS Store releases to follow.

Resettlement and Economy Balance

Hyperlane Breach Points and Hyperspace Slipstreams technologies now increase monthly automatic resettlement pop movement capacity by 25 percent. Transit Hub effectiveness for automatic resettlement has doubled to 200 percent. Wilderness Empires receive priority for Bloomed Biomass on Gaia worlds, and Augmentation Bazaars now grant access to Augmentation Merchants that combine Merchant and Executive benefits.

Interface and Quality of Life

Planet UI elements have received extensive layout fixes, ensuring buildings stay within their frames and district background sizes, paddings, and margins are evenly distributed. Pop Job production tooltips and details panels are significantly improved. Additionally, the Available Positions window in the leaders view now consistently starts closed.

Bug Fixes and Stability

Democratic Transference no longer grants excessive efficiency, and Augmentation Bazaars no longer claim incorrect trade increases. Biological ship empires can now grow Fledgling Dragons with the Here Be Dragons origin. Performance optimizations include a new mechanic for merging smaller, similar pop groups and calculating planet upkeep and production during monthly ticks to cache data for subsequent calculations.

Why this patch matters

Version 4.0.10 delivers performance improvements alongside quality-of-life adjustments that make managing populations and planetary interfaces smoother.
