Stellaris Launches 3.11.3 Eridanus Open Beta

Stellaris update 3.11.3 Eridanus is now available as an optional open beta on Steam. It fixes trait removal, refugee timers, and event loops.

Paradox Interactive has released the 3.11.3 Eridanus Open Beta for Stellaris on Steam. The optional test build addresses leftovers from the 3.11 update.

Opting In

The 3.11.3 Eridanus patch is an optional beta. To access it manually, open your Steam Library, right-click Stellaris, select Properties, open the Betas tab, and choose 3.11.3_open_beta from the drop-down menu. Save compatibility is not guaranteed between versions, and players encountering issues should test on a fresh, unmodded save before submitting a bug report.

Gameplay and Trait Fixes

Players can now remove the Plasmic trait from species to clean up the species tab. Refugees now trigger every 90 to 180 days instead of daily, and secondary species in random empires correctly receive habitability traits. Awakened empires are barred from using AI transports via global ship design country type restrictions. Civilian difficulty is no longer accidentally nerfed, and the Luminary Bloodline is now correctly inherited.

Event and UI Corrections

The Abandoned Gateway event now properly accounts for ruined gateways from Galactic Doorstep and Imperial Fiefdom origins. Council positions remain intact for Galactic Community members after adding civics. Expired leaders leave the leader pool only upon refresh, S875.1 Warform stays with their ship, the Grave Guardians no longer trap players in infinite first-contact loops, and the Kaleidoscope no longer double-dips trade income. Anomalies and dig sites now level up the Hyper Focus trait if a leader already has it rather than attempting to grant it again.

Why this patch matters

The Eridanus open beta addresses a wide range of long-standing Stellaris balance bugs and event loops, giving players a chance to test stability before the official public release.
