I suspect you're right. The reuse of a ship class is the kind of granularity that CBS probably isn't interested in pursuing. And it also throws a lifeline to fans who've spent considerable $ to create a set and then be told they can only use it twice.Yeah, I'm not at all clear on the what the first guideline prohibits. For example, I would guess that a film on the same class ship in the same time period with a supposedly different crew (but with the same actors, playing different characters) would avoid this restriction. Just need to make it clear that it doesn't continue a story from a previous fan film.
