We have identified an issue with Stack Auditor version 0.0.3 and the change-stack command. In some cases, the wrong application will attempt to change stacks if another application with the same name exists in a different space. A fix has been included in the latest release of Stack Auditor (0.0.4). It is recommended that all users of Stack Auditor no longer use version 0.0.3 and migrate to a later version of Stack Auditor.
