I belive the same thing happened with Phineas and Ferb Save Summer. That aired before The Klimpaloon Ultimatum which was referenced in the episode. I don't have the time to read every one of Dan and Swampy's tweets but I do believe one of them tweeted a reply to someone regarding that and said that they do not control when an episode is aired, the network does.
