The new Kusama runtime 1000000 introduced a XCM bug that can result partially executed XCM and stuck of funds.
I worked with Parity devs to debug and identify the root cause of the bug, create a Github issue described action items, a twitter thread explaining the bug, suggestion to parachain teams to workaround the issue. I also created a test script using Chopsticks to reproduce the issue, and use it to verify the fix.
I will also work with Fellowship to setup e2e tests and regression tests for future releases. But this can be considered out of scope of this tip.
So, when will there be a proposal for recovering the stuck fund due to this bug?
