title: Tortoise SVN Switch Branch Command Error - "Shares No Common Ancestry"
body: <p>When I try to do "switch" to change a directory to a different branch I get a strange error message. </p>
  
  <p>This is how repository is set up looking at it from the host's website. I used to have a branch called bugfix-lobby-quirks, but it was deleted after I merged it to trunk. This and the new feature-in-game-opponents-cards were both branched off of trunk.</p>

  <p>Now I want to take my checked out working copy "switched" from the deleted branch to this new branch. I have the bugfix-lobby-quirks branch already checked out on my computer since I was just working on it. What I want to do is switch everything in this folder to everything in the new branch I choose, which is nice since they aren't really all <em>that</em> different. This is what svn switch means, right?</p>

  <p>So then I click switch and a popup comes up. It automatically recognizes the branch and displays it in the list here so I choose it.</p>

  <p>Unfortunately, doing this leads to this error message every time.</p>

  <p>It's not a happy day. It's a sad day.</p>
  
  <p>Ok. So what am I doing wrong?</p>
