I found an errata item...
Expansion Kit errata section shows a correction to ship weapons fire: +2 for FC officers (page "80" pdf=85), and page "31" (pdf=36) matches
Starship Reference Sheet shows +3 for FCO (page not numbered, PDF=89)
Page 17 (pdf=22): Spring Rifle notes any rigel can use a spring rifle, or a military with Marksmanship 15+, pdf=90 implies mks 15+ for rigel.
Page 19 (pdf24): Telepathic Dog listed as "Telepathic Characters Only", reference sheet on pdf=90 shows "andromedans, taurans"
Page 29 (pdf 34):
"The Shielding Mechanism can
only be used with nuclear drive, not impulse drive, and thus Videni ships can
be followed by their ion trail while at hyperdrive."
"Impulse" should be "warp", as probably should also be hyperdrive.
Pdf 93 shows LtCdr commanding BC; PDF 89 shows minimum CO is Cdr, as does pg.26 (pdf=31)
