title: How do I update a CloudFormation stack with state UPDATE_ROLLBACK_COMPLETE?
body: <p>Is it impossible to update a CloudFormation stack once it goes into the <code>UPDATE_ROLLBACK_COMPLETE</code> state? I am using CodePipeline to deploy things. I find that once a stack goes into some invalid state, many times, I have to delete the stack manually and let it recreate everything again. Is that the right way to do this?</p>
