Making a custom persona that works in the campaign

[thefiremind]

I tried to make a custom persona, and it seemed all right, until I tried to use it in campaign mode. As you surely have already noticed, when a campaign battle starts, there's a nice animation that "carves" the avatar image by drawing a glowing circle around the persona's head. Well, with a custom persona that has no definition of that animation, the game hangs when trying to start a campaign match. I tried to look into the core, but I can't find where those animations are defined and/or stored. Any ideas?
