nice_rgb function missing in new version about scales HOT 2 CLOSED

I am having the same issue. Like yonicd, it's only an issue when loading a saved ggplot object. Here is my session info:

This unfortunately is one of the reasons you shouldn't save ggplot2 objects in rdata - there's no guarantee that it will work across versions.
