plot_anc_range.simple.R issue

[mprebus]

I have been receiving an error when trying to run the figure script in R for the biogeography tutorial:

Error: Names must not be of the form ... or ..j.
Run rlang::last_error() to see where the error occurred.
In addition: Warning messages:
1: replacing previous import ‘ape::rotate’ by ‘ggtree::rotate’ when loading ‘RevGadgets’
2: replacing previous import ‘ape::drop.tip’ by ‘treeio::drop.tip’ when loading ‘RevGadgets’

I am getting the same error, in my digging it looks like the error is thrown by tidyr::gather, as called by the function ggtree::nodepie, which is called in the function here plot_ancestral_states. This error is relatively new to tidyverse, according to the discussion here: tidyverse/dplyr#4094
