Update Notes for May 15, 2026 — Sins of a Solar Empire II Steam update #226031

Fixed bug that could cause corvettes near a fleet leader to slowly tumble through space. This was due to the orbiting attack pattern that would cause flip-flopping on physics goals. Fixed issue where allied AI players could end up in an endless tug-of-war trying to capture an object. This alters some of the capture mechanics: Capturable extractors and labs are now invulnerable. In cases where a human and AI ally(ies) are contesting a capture, the player will take precedence. In cases where it’s multiple allied AI players, the first player on the same team takes the capture with allies contributing. Note: We are aware of a bug where some Epic players lose their DLC. This is due to Steam client being open at the same time as the game (even if you don’t own Sins 2 on Steam). You can workaround this bug by closing Steam when you launch the game from Epic. It will be addressed in a new hotfix...
