It appears that several avatars (including my own, comment's, and LaRetta's) have gone missing. Others, including 360Works', still appear.

there was a system update that may have broken some legacy avatars or the location where they were stored - i found your image and restored it but i'd have to research the permanent solution.

 

Woo hoo - mine is back as well ;-)

Wasn't something that fussed me a great deal, although I had noticed it...

I also noticed that when a new account was created with an avatar (seen at the bottom of the main page-new member) their avatar appeared in place of either Mirror Works or FM Starting Point's avatar.  That was last night.
