Ok.. just what the hell is going on, here?

not much they can do… other than tell you to open a ticket.

so re-open the ticket, tell them that you’ve just used a character service, and are unable to pet battle.
(along with the other issues you’re experiencing)

this is why GMs aren’t meant to “fix” this sort of thing… because it often breaks other stuff.
issues like this need to be passed on to the devs.
