Flour can be from winter wheat or summer wheat – they have different properties which can explain why some doughs held together and others did not. Also, flour dries out when you store it too long. Always add a little moisture, water, milk, etc. when you get a crumbly dough – you are merely replacing the moisture that was lost.
