A proposal called [#129](https://kusama.polkassembly.io/referendum/129) was passed but had a problem. If too many messages were in one block, some would be lost, causing a loss of money. The Bifrost team found this issue and suggested not to use proposal [#129] because it would make the problem more likely to happen. Instead, they wanted to change a number called `ump_service_total_weight` back to a bigger number to avoid the problem. But then, proposal [#129] was stopped by the council, so the new proposal [#133] is not needed anymore. Thanks to the Acala team for helping with the test, and a problem was found that needs to be fixed.

Referendum can be rejected
