Creator's Apathy: In the final scene of the movie the Regis says that she'll go to Haydon Five to launch the Sensor Nebula and starting tracing Zor's missing battle fortress. The planet is referred to as Haydon-IV in all of the scripts, storyboards, artwork, etc. Even though the novelizations spell it as Hayden, they retain the correct number. Why wasn't this error caught and fixed? This trope.
What Could Have Been: After being bombarded with a ton of fan mail asking what happened to Rick Hunter, Lisa Hayes and all the other surviving Macross Saga characters Carl Macek and Harmony Gold decided to make their own new Robotech series, Robotech: The Sentinels, a kind of half prequel series that would have taken place in between the end of Macross Saga and the start of The Masters and shown the adventures of Rick and the old cast against a new cast (which included Vince Grant, a new character created to be the brother of Claudia Grant and father of Bowie Grant) as they ventured out into space and, presumably, would have eventually chronicled their return home. Sadly, the animation company in Japan that Harmony-Gold hired went bankrupt due to economic problems, forcing them to scrap the series after only finishing three episodes. These episodes were then turned into a direct to video feature, with the intended adventures of the series then becoming the basis for a series of expanded universe comic books and novels. For what it's worth The Sentinels video feature as it is does fill in some of the gaps when watched in its intended chronological order between Macross Saga and Masters, and as an extra bonus it gives the shippers the chance to see the wedding or Rick Hunter and Lisa Hayes.
