Description
This is apparently still happening rarely, opening this issue to track it further.
I don't know the exact cause but when it happens, semantic.min.css is missing some CSS rules which in turn breaks a lot of functionality in the UI. More investigation on what exactly is not being built is needed. I suspect a underlying race condition in Fomantic's build process.
Workaround is just to rebuild fomantic (make fomantic) until it produces proper files.
