Stellaris Open Beta v4.1.5 Overhauls Psionics, Origins, and Stability
Stellaris open beta version v4.1.5 brings together changes from the 4.1.4 test branch alongside desync fixes, UI updates, and psionic adjustments.
Paradox has launched Stellaris v4.1.5 under checksum c3d8 on the stellaris_test branch. This open beta combines previous 4.1.4 test features with targeted bug fixes for multiplayer desyncs, broken astral rifts, and espionage.
Multiplayer and System Stability
Version v4.1.5 resolves issues responsible for multiplayer desyncs and stops espionage and astral rifts from failing to function properly. A frequent crash linked to the shroud view during resyncs has also been eliminated, alongside fixes for saving and loading growth data.
Origin and Trait Adjustments
The Shroud-Forged origin now grants proper trait picks and points for its pops, allowing robo-modding without stripping existing traits, and sets them as the primary species upon full embrace. Mindwardens gain a dedicated Sol variant and prevent AI empires from selecting the origin. Resource Consolidation blockers now demand more time and resources to clear, such as a 2,500 alloy cost for prototype machinery.
Psionic Reworks and Balance
Psionic components receive multiple balance passes, including Shroud Seals applying a 50% fire rate penalty to psionic weapons within their system. Civilian ships now automatically upgrade to psionic shields correctly. The End of the Cycle covenant power Intensification now operates on a ten-year cooldown instead of exhausting on a single use.
Interface and Quality of Life
The resettlement window now displays clean integer job amounts rather than floating decimals. Unavailable ships are hidden from naval capacity ship size limit tooltips. Outliner sorting stability has been improved to prevent categories from shifting unexpectedly during tab changes.
Why this patch matters
This open beta refines complex internal systems, giving players a stable sandbox to test new psionic rules and origin balances.
