- The Council voted to fix an issue with Kusama's total issuance.
- Some KSM tokens were burned because of a problem with Statemine.
- A new update (v9040) will fix this issue and allow KSM to be counted again.
- The fix involves setting the balance of a special account to match the KSM in Statemine.
- The Council acted quickly to prevent more KSM from being lost during the fix.
- The Apps team will re-enable a feature called `teleport` after everything is fixed.
- This ensures that KSM tokens are properly accounted for and can be used again.
