Errors after renaming a rack

I tried to rename a rack via the web GUI. Subsequently, I got a generic error when I clicked on an app in that rack: An error has occurred while loading this content. I named it back to the original name, but same error. Also, now when I try to access anything in that rack via the CLI, I get this error: Ambiguous rack name. And, when I try to view the environment via the CLI I get this error: NoSuchKey: The specified key does not exist.

Has anyone else successfully renamed a rack and/or know how to resolve these issues?
