ols_plot_resid_stud() fails to plot the very cases it is designed to identify.
Changing the y-axis scale range fixes the problem - i.e. p + scale_y_continuous(limits=c(0,20))
p$data
Below is the ols_plot_resid_stud() data object. As you can see, case 64 is an outlier yet fails to appear in the plot. I would consider this a pretty serious issue.
