This updates the css-copy and js-copy tasks to first remove their respective directories, create them again, and then recursively copy over subdirectories and files. This is the only way I've been able to fix the syncing issues I've faced on macOS that don't appear on Windows. Could be a bug in how we cross-env-shell/shx works here?
@MartijnCuppens Can you give this a go locally? I did some obvious changes in the source scss/**/*.scss
files and saw them sync pretty quickly and without issue on my end. Still have the Hugo crashing at times and not wanting to restart though.
