After I click "OK" to that message, all of the clips on screen will read "Sample Offline" instead of having a waveform in them.
The weirdest part is this. To fix it, I have to either render each clip down, save them to disk again, and then replace the temp clips with the rendered ones, OR I have to hit the "replace" button on one of the clips and point it to the correct file. At that point, all of the samples come back "online."
Should I submit a screenshot? Unfortunately I can not send the liveset because it won't let me save it in that state
