Short description of error
File needs to be saved in order for cycles to render smoke to file. It works in viewport render, but not when doing an F12 render

Exact steps for others to reproduce the error
Start new scene
Set render engine to Cycles
Select Cube
Add Quick Effect Smoke
Play a couple frames so you can see smoke in the viewport
Render with F12
The result is just a cube with no smoke
