Rainbow Six Siege Y11S3 Addendum Covers AI Bot, Weapon Sight, and Pulse Fixes
The Season Test Server fixes also address Montagne's Le Roc Shield, playlist settings, Operator Guide images, and voice chat.

Rainbow Six Siege has a fresh set of bug fixes for its Y11S3 Season Test Server. Ubisoft’s Y11S3 patch notes addendum covers gameplay problems, operator issues, user interface bugs, and an audio setting that could carry into matches incorrectly.
AI training bots receive several corrections. They will deal with Azami’s Kiba Barriers properly, appear in the Yacht map for the Clear House playlist, and rappel at the intended speed. The update also addresses aiming down iron sights with the Bearing 9 and Super Shorty, along with tutorial objectives in the Shooting Range that could not be completed.
Operator fixes cover Montagne’s Le Roc Shield animations and Pulse’s Cardiac Sensor. The addendum also cleans up several menu and customization problems, including unavailable horizontal grips, missing Operator Guide images when using keyboard arrows, and match settings that could become inaccessible after taking over as Squad Leader.
There is one crash fix for 3v3 Arcade. If players selected the same Operators, the game could crash when the match ended. Voice chat is also corrected so disabling it from the main menu keeps the setting disabled after a match begins.
