So...this started when the "choose outfits" was instituted and has gotten progressively worse throughout the day. I haven't changed my HA since this happened, it was appearing fine earlier, and is suddenly broken on forums again. More and more HAs are disappearing as the day progresses.

[edit] So my HA suddenly returned, but this has been an issue off and on all day.

Also the site is lagging insanely - to the point where I keep having to close the tab and reopen it to get something done (like use a costume trunk - looking at you crumbling yellow brick).

Thanks :) After the temporary down time it seems to be running better.

Locking this up as resolved! :)
