Wan 2.2 default workflow – CFG input disconnects from KSampler on load (No link found in parent graph for id [129:85] slot [7] cfg)

Not a critical issue, but consistent and reproducible.

Latest ComfyUI update appears to break the default Wan 2.2 workflow. The CFG input on the KSampler node is disconnected on load every time.

Even after manually reconnecting:

Saving the workflow does not persist the connection
Loading from an image with embedded workflow also results in the same disconnection

Error shown:
No link found in parent graph for id [129:85] slot [7] cfg

Steps to reproduce:

- Load default Wan 2.2 workflow
- Restart ComfyUI
- CFG input is disconnected

Workaround is just reconnecting manually, but it happens every launch.

Just reporting for awareness.

Start by reproducing the issue with the default Wan 2.2 workflow, then trace the load and save paths for the KSampler CFG connection, including workflows embedded in images. Done means the CFG input remains connected after restart, saving, and reloading from an embedded workflow without the reported parent-graph error.
