Mozzie is currently disabled in all game modes in Rainbow Six Siege due to newly discovered bugs affecting his gadget and/or interactions introduced with the latest update, so Ubisoft has temporarily deactivated him while they investigate and work on a fix.

What ā€œMozzie disabledā€ means

  • Mozzie cannot be selected in any playlist or mode right now, including casual and ranked, because he has been globally deactivated serverā€‘side.
  • This is not a lore change or permanent removal; it is a temporary gameplay-side shutdown tied to technical issues.

Why operators get disabled

When an operator is suddenly disabled like this, it is almost always because:

  • A severe exploit appears (for example, unintended invincibility, map breaks, unfair info, or crashing lobbies).
  • A new event, mode, or patch introduces a conflict with their gadget logic (Mozzieā€™s Pests interacting with new gadgets, drones, or event rules, for instance).
  • The issue is big enough that hotfixing in place would be risky, so the safer move is to turn the operator off until a tested patch is ready.

The current community discussion around Mozzieā€™s deactivation frames it as ā€œyet another classic set of bugs introduced for absolutely no reason,ā€ which implies a bug/exploit scenario rather than a balance nerf or design choice.

What to expect next

  • Mozzie will typically be reā€‘enabled in a later hotfix or title update once Ubisoft confirms the bug is fixed and the operator passes QA testing.
  • Patch notes or a short post on official Siege channels usually mention when an operator is temporarily disabled and when they return, so checking those is the best way to see when Mozzie is back.
