Ubisoft published an additional set of Y11S3 Test Server fixes for Rainbow Six Siege on September 1. The list is focused on broken functionality rather than balance: it repairs weapon customization, operator gadgets, AI training behavior, menus, and an Arcade crash.
Two operator issues are resolved
Pulse receives the most consequential operator fix in this addendum. His Cardiac Sensor had stopped displaying enemies it detected, preventing the gadget from delivering its core information. The notes say that behavior has been corrected, but they do not describe any adjustment to detection range or other operator values.
Montagne’s change is narrower. The extend and retract sequences for the Le Roc Shield have been smoothed out. Nothing in the announcement indicates a mechanical buff or nerf to the shield, so this should be treated as an animation repair rather than a change to his place in the operator meta.
Weapon and training problems
Players using the default iron sights on the Bearing 9 or Super Shorty could not aim down sights. The patch addresses that input-breaking issue. Horizontal grips, which had been unavailable when customizing weapons, are also available again.
The training environment gets several corrections of its own:
- previously blocked Shooting Range tutorial objectives can now be completed;
- AI bots spawn on Yacht in the Clear House playlist;
- bot rappelling is no longer unusually slow;
- bots attempt to destroy Azami’s Kiba Barriers instead of always navigating around them.
These are not weapon-stat changes, but they matter when using training modes to test recoil, positioning, or operator setups. In particular, AI reacting directly to Kiba Barriers should make those practice situations less dependent on broken pathfinding.
Arcade stability, menus, and audio privacy
A crash at the end of a 3v3 Arcade match has been fixed. It occurred when players selected duplicate operators, making the result especially relevant to a mode that allows team compositions not seen in standard play.
The remaining user-experience fixes cover several unrelated annoyances. A player promoted to Squad Leader while viewing the Essentials playlist tab can change match settings again. Operator Guide images should load while browsing with keyboard arrow keys, rather than leaving incomplete guide pages.
Ubisoft also corrected a voice-chat setting problem. Disabling voice chat from the main menu did not keep it disabled once a match began. Players who use that setting for privacy should still confirm it after updating, but the client is now expected to carry the selected state into the match.
What this means for players using software
This addendum does not announce an anti-cheat revision, new HWID checks, detection changes, or enforcement measures. There is consequently no evidence here that a different spoofer is required or that the ban system itself has changed.
That does not make a client update irrelevant to external software. A bug-fix build can still move offsets, invalidate signatures, or prevent an injector, ESP, or aimbot from initializing correctly. Do not assume that a build working before the update remains compatible afterward. Close the game, check the software update status page, and wait for explicit version support before loading anything.
The Rainbow Six Siege catalog for current builds is the appropriate game-specific reference, although a listing should not be treated as confirmation that every update has already been checked. Since these notes describe Test Server work, compatibility conclusions should also remain separate from the live client until its own build is verified. Skipping an early session is safer than testing stale offsets on an account you intend to keep.
