It looks like badges are no longer showing on users when browsing questions/answers:
The badges appear while the pages loads, but as soon as the mathjax fully loads, they disappear. Checking other SE sites, it appears to only happen here; I can't reproduce on other sites. It seems to affect both questions and answers.
Has been reproed by 2 other users. I'm on Windows 10, using Chrome, with no userscripts active.
