please keep this bug report cause the new heatmap has a bug.
i've experienced on multiple different coasters that (occasionally) there is no redrawing of the live data heatmap and no refresh of the previous run heatmap on further test runs.
I am not sure when this can happen, but chances are high that you get this bug when a test with heatmap runs while same time you're inside camera mode of that coaster.
Btw, the switch between live data and previous run could have been a much nicer idea if the old heatmap version would have been kept inside (by adding the option "Live rewrites Previous" to the heatmap data selector).
Moreover it would be a less annoying feature if the selected data type is the default data type for all available heatmap types.
Cause if you want to "analyze" a heatmap, usually you would check the different heatmap types (fear, excitement, nausea, ... ) of the same run. And not "how was Excitement in the actual run? Ok, that looks good, so let's check Fear of the last run in comparison."
