You've been ordered to appear in court, so of course you still have to appear in court. You can contact the court any time you want to verify the status of the hearing.

I have no way of knowing how things "crossed in the mail", so to speak, and am not going to guess - that can't help you and, if I'm wrong, could harm you. You're being advised by a lawyer, and you have an unusual set of facts, so I suggest you consult your lawyer about this.
