Rainbow Six Siege players received an addendum from Ubisoft detailing fixes found on the Season Test Server during Year 10. The update, presented as a Y10S3 patch notes addendum, lists gameplay, level design, operator, user experience, and audio fixes discovered while testing.
The addendum groups a long list of “FIXED” items that come from test-server reports and automated checks. Several entries deal with AI pathing and bot behaviour, while others correct visual or level-design issues such as lighting and non-destructible wall placement. Operator-specific fixes include aim timing and ability visuals, and the user experience section addresses navigation, esports pages, and playlist stability. Audio and melee SFX problems are also called out.
These changes may appear in a future live update or be folded into the broader Operation High Stakes release, depending on final validation. Players who use the test server should notice fewer animation and bot-related interruptions after the changes are applied. No firm live release date is provided in the addendum. For the full Operation High Stakes patch notes, see the Operation High Stakes patch notes.
