The issue stems from how the game handles animation priority when interacting with Rook's armor pack. Ever since Operation Brutal Swarm granted the passive "Withstand" self-revive mechanic to any defender wearing Rook ceramic plates, the gadget's code has been heavily tied to health states, down-but-not-out (DBNO) flags, and client-server synchronization.
The exploit required a defender to trigger the plate pickup animation while interrupting an environmental vault or barricade tear-down simultaneously. This split-second input race condition tricked the engine into applying the armor health buff while leaving the player character in an un-synced animation state.
On the player’s screen, they could fire normally. To the opposing team and the game server, the operator model remained stuck in an invulnerable revive state with broken hitboxes. When attackers attempted to shoot the glitched defender, the server encountered thousands of conflicting hit-registration calculations per second. The game client would throw error code 2-0x0001900C, immediately booting players and crashing the match instance.
| Incident Phase | Observed Date & Platform | In-Game Impact & Server State |
|---|---|---|
| Exploit Discovery | October 12, 14 | Clips show invulnerable defender states during DBNO animations in casual lobbies. |
| Ranked Proliferation | October 15 | Exploit adopted widely to force server crashes and prevent MMR losses during losing matches. |
| Emergency Ban | October 16 | Ubisoft locks Rook in all playlists; operator icon displays greyed-out padlock. |
| Server-Side Mitigation | October 18, Present | Backend checks applied to drop illegal packet loops; full client patch undergoing regression tests. |
