Highend hb-moon icons disappeared after 2.4.1 update

I’ve tried looking for a resolution to this issue, but to no avail.

I recently updated Highend to 2.4.1 and now the hb-moon icons on all of my pages are either blank or show a vertical rectangle where the icon used to be.

I have cleared the cache in my browser, used different browsers, and they still don’t show up. The only place I see them is on the mobile version of the site, but that’s it.

Any help would be greatly appreciated.
