Apologies if this has been covered in another thread - I have tried searching and not found anyone with the same issue. It may also be me being stupid rather than a bug/game issue! If so I would love help XD
I have grain in a granary, next to a windmill, workers in the windmill, and builders and labourers available. The windmill will not process the grain - the workers’ status shows ‘Idling - Unable to Work’.
I have tried kicking the workers out and then re-staffing the windmill.
I also have a staffed bakery, if that’s relevant.
