    Mehh, I have a rough idea were this comes from. Thank you for the ping 🙃

    @rustbot claim

    For context/as a side note, this can only happen if lint_reasons are enabled. Therefore, we don't have to revert that PR :)

    I think I just have to remove that assert all together. I'm guessing that the comment only runs part of the compiler, but not the query used to update the unstable ids. The next step will require some refactorings. For now, I'll remove the assert and look back into this after the refactorings. Thank you for the report!
