Reaper Render Length Mismatch

Reaper Render Length Mismatch

I had a frustrating experience while doing test renders for the new album.  The length of the rendered file was actually shorter then the length of the source material.  I ended up playing with a number of different render settings trying to figure out what was going on.

Suddenly I found what the culprit was, the playback rate control had been bumped slightly.  

I know this seems simple but it is the simple things like this that will cause you to pull your hair out when you are in the final stages of a project.  Posting this here in hopes it saves someone else some frustration.
