Rainbow Six Siege Y11S1 Patch Addendum Fixes Solid Snake and Dual Front Bugs

Ubisoft has released a patch addendum for Tom Clancy's Rainbow Six Siege Y11S1 Test Server, addressing dozens of bugs tied to Solid Snake, the Soliton Radar Mk. III, and Dual Front mode. The update clears up radar elevation detection errors, OSP Pouch hud highlights, and Maverick breaching torch issues.

The latest Tom Clancy's Rainbow Six Siege patch addendum for the Y11S1 Test Server targets a wide array of technical issues, ranging from operator gadget anomalies to UI glitches.

Solid Snake and Soliton Radar Fixes

The update resolves multiple issues with Solid Snake and his gear. Solid Snake's OSP Pouches no longer display incorrect alliance colors when pinged, get stuck in clear house training mode, or trigger device notifications for attackers walking over them. HUD highlights for two gadgets simultaneously when using the OSP Pouch have been corrected. Furthermore, the Soliton Radar Mk. III will no longer incorrectly detect the second floor when standing on the Emerald Plains rooftop, nor will it detect the basement when crouching near the Bank garage ramp.

Gadget and Dual Front Mode Corrections

In Dual Front mode, Maverick's Breaching Torch now starts with its proper charge count instead of one and will refill after depletion. Denari no longer triggers a network deployment notification for all players simultaneously. Additionally, interaction gauges now fill completely before deployment animations finish, and operator leg positioning during face-down rappelling has been fixed.

UI and Audio Cleanups

Several quality-of-life interface problems were addressed, including black spectator bomb objective outlines and placeholder text for Finka, Thorn, Iana, and Kaid in the operators menu. Custom game lobbies no longer automatically disband at the end of matches, and Thatcher's EGS Disruptor graphical corruption on detection screens has been cleared. Audio bugs, such as missing pickup sound effects for local custom match hosts and missing feedback when Rauora's D.O.M. Panel is hit by Thatcher's disruptor, have also been patched.

Why this patch matters

This addendum mends critical gadget tracking and map boundary misfires for test server features, laying a cleaner foundation before the season moves to live environments.
