Running RT 3.0.81 and I am not able to display an overlay when using a recipe. I’ve tried stoping and re-starting the software (that has worked with other issues) but this seems to be a feature, not a bug. Once I start roasting in recipe mode, if I go and preview a previous roast, the overlay button is grayed out and 
hover-over so not available. If I set an overlay before starting a recipe, once viewing the roast, no overlay is shown so it seems to remove it.
Seems the only way to see an overlay is to not use the recipe function, or am I missing something?
