Acala co-founder Bryan Chen posted on the X platform that there is an XCM bug in the new Kusama runtime, the funds are safe, and some governance proposals will be put forward to unlock trapped funds.
Bryan Chen said that he received reports that users did not receive KSM on Karura when making XCM transfers from Kusama. Execution on Kusama's side appears to be successful, but no funding has been received on Karura's side.
After investigation, it was found that this issue started to occur after the new Kusama runtime upgrade. The e2e-tests integration test suite also confirmed this issue.
