The administrator at Cloud Kicks built a flow in a sandbox.

Flows deployed with change sets are inactive by default and need to be manually activated in the destination org before they can run. Deploying or redeploying a flow with change sets creates a new version of the flow in the destination org, which preserves the previous versions and allows for rollback if needed. All flow dependencies, such as custom fields, objects, or variables, are automatically added to the change set when a flow is added
