title: Visual Studio 2012 project lost link to TFS
body: <p>So I came back to a project that I was working on a few months ago, and when I load it one of the projects seems to have lost the link to it's entry in TFS. The solution explorer doesn't show the lock icons for it, but I still see it in TFS. </p>
  
  <p>I tried performing a add to source control but it says that the items already exist.</p>
  
  <p>Anybody have ideas on how to fix this? </p>
  
  <p>I'm trying to avoid remapping because there are a few branches, and I'm not even sure that will fix it.</p>
