+> **Note:** If you experience validation errors when loading example workflows, try creating a new workflow from scratch by adding the nodes manually. Ensure you're using valid samplers (like "euler", "euler_ancestral", etc.) and schedulers ("normal", "karras", etc.).

 - Improved parameter handling
