Ah nevermind! I’ve got it.

I custom downloaded an updated version of Modernizr and only put CSS3 and a few HTML5 things in the build. No JS or shivs. So something in there IS breaking the group avatars for future FYI in BuddyPress Groups – but for now, this is fixing my issue. Now if you need some JS or a more extensive Modernizr, then yeah, you may come across issues.

Hope it helps:
