It does seem like it. But just to be sure and keep it locked after the change: Do you know any official sources that has refer to the episode as such? The episode has not aired yet, so the Adult Swim website does not have it listed.

I found the episode titles tweet and it indeed shows an additional "n" so I've updated it. I also updated the episode airdate and number since the Adult Swim schedule (when sorted by show) has A Rickconvenient Mort as the episode airing on July 4, not Rickdependence Spray.
