Character added but cannot post as character

Not sure if this has come up before but I added a new Non Player character to a game, but it's not showing in my list for the game it's been added to.

It needs an avatar, a name in the name field of the sheet, and the avatar has to be "legal", like not an obscure format.

Fixed it already, but that was the problem. I'd entered all this but seems I hadn't saved it correctly. Working now.
