Stellaris Open Beta v4.1.6 Fixes Crashes, Fleet Clogging, and Ringworld Stats
Stellaris open beta v4.1.6 is now live on the test branch with bug fixes, ringworld economy adjustments, and stability improvements.
Stellaris version v4.1.6 is available as an open beta on the stellaris_test branch under checksum db3e, building on v4.1.5 with stability fixes and balance adjustments.
Fleet Management and UI
Teeth of the Eater fleets now move to merge with existing fleets on spawn to prevent map clogging. Planet governor skill modifiers no longer apply to fleets, and the proper leader tier frame displays again in the UI. Tooltips are added to the Great Awakening tradition for Psionic Assimilation, the Automation Building for Tankbound, and the Broken Shackles planet UI. The Symbiosis living standard tooltip no longer displays a string ID.
Empire Balance and Civics
Disciple of the Cradle leader trait no longer removes job output as a governor and now adds a trust cap as a councilor. Shroud-Forged pops can now be recruited as Assault Armies or Psionic Armies, and Radiotrophic pop upkeep now applies correctly. Cybernetic ascension as a Hive-Mind now properly blocks Psionic Ascension, and Hard Reset Empires that began Cybernetic ascension can no longer take the Synthetic Evolution ascension perk, and vice versa.
Planets, Districts, and Ringworlds
Distributed Design Center and Metallurgical Research Lab buildings now grant correct additional bonuses on ringworlds. Alloy Nano-Plants and Civilian Repli-Complexes no longer have increased costs and upkeep on ringworlds. Ecumenopolis Urban Districts now add Production Overseers jobs. Terraforming a planet into a machine or hive world no longer removes buildings in rural districts. Ocean Paradise starts now show farming districts correctly at game start. The Council Cleanup event will no longer attempt to create pops on stars.
Stability and Modding
Fixed crashes to desktop occurring in the set_hostile effect, on macOS when highlighting demographics pie charts, and when exploring astral rifts with prior progress. Modding tools remove duplicate uncapped district types in favor of an is_uncapped trigger. The overnight command now retains two extra saves at 2275 and 2325, and a new -incrementalsaves command line parameter keeps additional saves at key game milestones for non-Ironman games.
Why this patch matters
Beta v4.1.6 targets critical stability crash vectors while smoothing out ringworld economies and ringfencing mutually exclusive ascensions.
