Summary: As reported by @bb and @Angen ,375c319639broke formation walking in a few situations. The issue is that f489ab3a16/D2871 requires formation members to get no messages until the controller is stopped, but375c319639didn't use the correct function (on account of a missed rebase), so members stopped too early.
