Its very clear to me that content types after they are deployed their inherited lists shouldnt be changed manually using the web gui.
“Do not, under any circumstances, update the content type definition file for a content type after you have installed and activated that content type. Windows SharePoint Services does not track all the changes made to the content type definition file. Therefore, you have no reliable method for pushing down all the changes made to site content types to the child content types.”
In the current project I am suspecting that some changes were done to the content type after the deployment and activation, and I need to know in which lists the link to the parent content type definition is broken.
Tells me for each content type, its usages, but what I need to know its if for a list the inheritance link is broken or not.
