I have noticed this bug once previously (that time it was with the Carpenter). This time the Weaver seems to have stopped crafting / got stuck on the ‘Fire Quiver’’ that is currently queued.
As far as I can tell from the pre-requisites page the materials are all present and available.
As I am not sure what might be causing it (I have not excluded user error!) I thought you would probably want the save file uploaded. So please find it attached. In parallel I will see if I can kickstart the crafter.
