Cannot unfollow renamed BitBucket projects.
I renamed project on BitBucket end. This caused CircleCI to redirect the project to a 404 page. In addition, I cannot unfollow/delete the CircleCI project, as even the settings page redirects to 404.
UPDATE: I was able to unfollow the project via the API
curl -X POST https://circleci.com/api/v1.1/project/bitbucket/username/projectname/unfollow?circle-token=:token
