It looks like some of the premade ships for the ALtarians have some kind of issue with required techs. They show up in the list as requiring one more tech than is listed, like it's a broken like or something, and then you never can get them to become available. I started noticing this with the large hulls. It's not a huge problem, but I thoguht I'd post about it to give those devs that handle this kind of thing a heads up. Oh I'm running version: .95(.002
