Avatars work occasionally

Seems like avatar support for users on other networks (i.e. AIM, YAHOO, etc) is only working some of the time. Anyone have any ideas as to what might cause this? For example, right now I only see green circles as the users avatar or yellow circles if they are away. If I mouse over their entry, the “card” that pops up has the outline of a person instead of their avatar.

This was working at some point, and I’ve noticed in the past that it would work for a while and then stop working.

I am having the same issue right now and have submitted a Support issue for this.
