Fire suddenly not rendering (But shows fine in rendered preview..)

…As it says really, not sure what I’ve done to manage this, been playing around with fire fine the past couple of days, now if I do a render the fire isn’t there, although it’s visible in the rendered preview.

I’ve baked the sim… Any ideas what to check?

Sorry for starting with the obvious, but did you make sure this https://raw.githubusercontent.com/ChameleonScales/Blender-individual-icons/master/PNG-16x16/ICON_SCENE.png is enabled in all the right places ?
