Is r-AppVeyor currently not using the latest version of remotes (with 800ca64 included)?

Because I am still getting the same issue:
https://ci.appveyor.com/project/IndrajeetPatil/ggstatsplot/build/job/4dpn016hchn8qd2v

This time it is concerned with dplyr and pillar-

And dplyr can't be downloaded because pillar is not found-

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  there is no package called 'pillar'
Calls: <Anonymous> ... loadNamespace -> withRestarts -> withOneRestart -> doWithOneRestart
Execution halted
ERROR: lazy loading failed for package 'dplyr'

Error in i.p(...) :
