I'm not sure if anyone else is having this problem. Usually my avatar is at the top of the page next to the Gaia Online logo, but recently it hasn't shown up, is this an update I missed or just a bug?
EDIT: Ok, it's also not showing up for me on my post...
You show up just fine for me. Do you possibly have Adblock or a similar addon enabled? That might be blocking your avatar?
If not, try clearing cache and making sure your browser and flash player are up to date?
It also sometimes happens when you try to equip three or more items in an animated state that they end up just making the avatar invisible (been happening this way since the Spirit of Summer event)
