The **Composable Finance** team has had [the same issue](https://kusama.polkassembly.io/motion/427) essentially as on Picasso chain on Kusama, so one particular cause: The team had a stray [todo!](https://github.com/ComposableFi/composable/blob/094d4668400c7832ccd601863a175eeb931782e3/runtime/picasso/src/weights/democracy.rs?_pjax=%23js-repo-pjax-container%2C%20div%5Bitemtype%3D%22http%3A%2F%2Fschema.org%2FSoftwareSourceCode%22%5D%20main%2C%20%5Bdata-pjax-container%5D#L117) in the weight calculations for pallet-democracy [which doomed the chain to be bricked once the launch period elapses](https://github.com/paritytech/substrate/blob/542a8585339d2581e641df339d254d7dd22b1456/frame/democracy/src/lib.rs?_pjax=%23js-repo-pjax-container%2C%20div%5Bitemtype%3D%22http%3A%2F%2Fschema.org%2FSoftwareSourceCode%22%5D%20main%2C%20%5Bdata-pjax-container%5D#L1758-L1763).

Schedule the currently externally-proposed majority-carries referendum to be tabled
immediately. If there is no externally-proposed referendum currently, or if there is one
but it is not a majority-carries referendum then it fails.

The dispatch of this call must be `FastTrackOrigin`.

- `proposal_hash`: The hash of the current external proposal.
- `voting_period`: The period that is allowed for voting on this proposal. Increased to
  `FastTrackVotingPeriod` if too low.
- `delay`: The number of block after voting has ended in approval and this should be
  enacted. This doesn't have a minimum amount.

Emits `Started`.

Weight: `O(1)`

Set the storage for the parachain validation code immediately.

- The Composable Finance team had a problem with their software on the Picasso chain.
- They found a mistake in the code that caused the chain to stop working.
- They have fixed the problem and released a new version of their software.
- They have also submitted some information called a preimage.
- You can find more details in the original post.
