We are getting this error when we try to merge from a development branch (Dev) back to its parent branch (Main). Main did have some changesets rolled back a few weeks ago which included the deletion of some folders which exist in Dev. We believe this is the source of the problem. What is the best way to resolve this. Main should pretty much match up with Dev but currently it is missing some sub folders. How can I get these folders / files to move from Dev to Main? We are trying to manually resolve the changes but it is a bit of a mess. It hard to believe that TFS makes things this hard to resolve.
