Stellaris 4.0.8 Patch

Stability

• Fixed a circular dependency in the French localization that would cause a crash.

We will continue to work diligently on this release to bring you the quality you deserve. Please continue to post any issues you find in the Bug Reports section of the Stellaris forums. The more details there are, with attached save games, the more likely we'll be able to fix it. Until next time, bye! Edit: One more for tonight. A 4.0.9 hotfix has also been released, reverting an OOS fix we attempted for (COUNTRY_RESOURCES) that was causing incredible performance issues. We will attempt to have a comprehensive fix for the COUNTRY_RESOURCES OOS in the patch planned for this Thursday.

Stellaris 4.0.9 Patch

Performance

• REVERTED an attempted fix for an Out-of-Sync error (COUNTRY_RESOURCES) that was causing serious performance issues.
