There is nothing missing that I know of in my dashboards - all working as it has always been. So maybe watchman is reading some old yaml or something somewhere ?
I have removed it for now. And then got AI assistance to remove all the places it was left behind causing errors in the logs. I also took that as a sign to remove all HACS things that I really am not using / dont really need. Go go as close to base as possible and a clean system.
