Here are a few random errata:
Prowler MTV (sealed) -- I think Comstar should only have this in LSW era? It's standard rules tech and TRO3085-Suppl. (p. 114) suggests its custom made by Mitchell Vehicles for the Explorer Corps
Devastator Tank and
Schreck PPC (introtech versions) -- should Comstar have access to these (in addition to existing factions) in ESW and LSW eras? Both are produced at Aldis-Terra and exported during the LSW era.
Mauna Kea (standard) ship -- looks like it's missing availability for IS General and Periphery General for LSW eras (has it before and after, and broad access is consistent with TRO3039 fluff).
Star Dagger S-2B fighter -- I think rules should = Introductory, according to FR:DCMS 2765 (p.20)
Ailette Zero-G exoskeleton (Sqd4) -- should the Taurians also have access? Produced by Taurus TI on Taurus, according to TR:VA
Tunnel Rat IV Combat Exoskeleton -- this looks to be a duplicate MUL entry, relative to the Tunnel Rat IV Mining Exoskeleton entries. It's only mentioned in passing in the General Motors entry in Masters & Minions (p. 42), and its description is consistent with the TR:VA description of the Tunnel Rat IV on p. 229, which is covered by the Mining Exoskeleton MUL entries.
Lancelot LNC25-01sl -- I think this one fell through the cracks with the following earlier errata. Rules level should be "Standard" as with the others (see ER: 2750, p. 136)
Changed tech level of CRB-27sl from advanced to standard
addendum: this error affected a handful of other units from ER:2750
