Not a big deal, but when on the nav-map, you zoom into a system you aren't in, the text on the right defaults to "You are located in this sector." As I'm not even in that system, I don't think it likely that I'm in a sector in that system.

Not likely but possible given folded-space technology. Are you sure you weren't thinking of going to a sector in that system?

Along with Guild's patented OCF technology, they have also developed the "SEER-Nav" system.
