Hmm, now that you mention it I’m seeing the same thing on my subdomain blogs (using a rev of 2010 theme on subblogs, wih bp-default/minor child customizations on my main site). Gravatars still show up, but not user defined avatars. My most notable change as of late has been BP 1.2.6.

@topracer, what bp rev are you running?
