Icons not displaying in production

[ctilley83]

icons don't work in production

less-rails-semantic_ui gem: version 2.2.2.0
ruby 2.3.0

I followed the instructions in the readme precisely, but while in production, icons are not being displayed.

rails assets: precompile
It seems that the icons are being compiled, but not displayinng in production. A placeholder image is viewed in firefox and chrome, but is blank in safari.
