If every word that came out of Mongoose had to be vetted and thoroughly checked over for consistency, nothing would ever get published. I think what Mongoose, and all the other Traveller associated companies, have managed to but together is actually quite impressive. There are inconsistencies and mistakes everywhere, not everything works that well, and therefore you have use your own common sense when refereeing. I'd rather have a big complex universe with deep history and a lot going on, than have a small simple place that works flawlessly. Because that's the choice here.
