Tom Clancy's Rainbow Six Siege Y11S3 Addendum Fixes Operator Gadgets and Crashes

Ubisoft details the test server fixes for Rainbow Six Siege Y11S3, addressing broken iron sights, crashing 3v3 arcade matches, and malfunctioning operator abilities.

The Y11S3 patch notes addendum for Tom Clancy's Rainbow Six Siege collects the bug fixes tested over the course of the season's Test Server period, targeting critical crashes, operator gadgets, and training modes.

Operator and Weapon Fixes

Pulse's Cardiac Sensor now displays detected enemies correctly. Montagne's Le Roc Shield extend and retract animations run smoothly. Iron sight aim down sights issues for the Bearing 9 and Super Shorty are resolved, and horizontal grips are back for weapon customization.

Gameplay and AI Training

AI training bots no longer attempt to punch through Azami's Kiba Barriers instead of navigating around them. Bots now spawn on the Yacht map during Clear House matches and move at normal speeds while rappelling.

UI and Match Stability

Selecting identical operators in 3v3 Arcade matches no longer crashes the game upon completion. Squad leader permissions in the Essentials tab, keyboard navigation for Operator Guide images, and voice chat bugs when disabling audio in the main menu are all fixed.

Why this patch matters

This addendum clears out a dense backlog of bugs, restoring reliable functionality to Pulse, Montagne, and weapon loadout menus.
