title: Prefabs & scripts missing after using source control to move Unity project to a different machine
body: <p>I've been working on a small project in Unity over the past few months, using Git for source control along the way. I recently got a new laptop which is being demo my progress in different locations.</p>
  
  <p>I installed Unity &amp; all the relevant runtimes needed within the application and pulled the source down to the new machine. The project opens in Unity, but the Hierarchy view shows this where my prefabs used to be.</p>

  <p>All of the resources (prefabs, models, scripts) are in the same directories as they were on the original development machine, but are somehow becoming "unlinked" during the process of pulling them down to a new machine.</p>
  
  <p>I have tried searching but have been unable to find a solution to this particular problem shy of just recreating everything.</p>
  
  <p>Thanks for the help.</p>
