Can't have discrete scale before continuous scale about ggnewscale HOT 2 CLOSED

I think that's the expected behaviour, isn't it?
Stat/geoms defined before adding a new_scale() use the scales added before the new_scale() call. So if you add geom_contour() after new_scale() you need to add its scale also after new_scale(). Like so:

ggplot(mapping = aes(x, y)) +
  # Add geom of measurements
  geom_point(data = measurements, size = 3, aes(color = as.factor(thing))) +
  # Add scale for measurements
  scale_color_discrete() +
  # Add a new scale
  new_scale_color() +
  # Add geom for topography
  geom_contour(data = topography, aes(z = z, color = stat(level))) +
  # Add scale for topography
  scale_color_viridis_c(option = "D") 

Does this clarify the issue? Is this related to this issue? Let me know if there's anything else I can do :)

Whoops, you are totally right, this was just me being silly and forgetting to remove the viridis scale when I swapped the first plot to the discrete color. It came up while I was trying to fix willgearty/deeptime#2, but I don't think it's actually related.
