The devs are having a hard time reproducing this issue. Are you still having the issue? Also: I know this is a total kludge workaround, but if you have a game with the character in it, you could copy it over to production to export the character to the live character vault. With a lot of characters, that's not ideal, of course, and we'd like to solve your issue rather than have you using a workaround. But it's an option for now.
