Yes, there was errata to Supplement 3. It is called the
Spinward Marches Campaign. SMC added stellar data and made many minor changes to the UWPs (including the accidental deletion of one world!).
The
Imperial Encyclopedia put the missing world back and updated the allegiance codes for the Rebellion. MTJ#3 (which was produced by DGP, but contains GDW copyright) reprinted the
Imperial Encyclopedia information along with data for the other three sectors of the Domain of Deneb.
Finally, the data was again collected into the
Regency Sourcebook for TNE. The RSB's "1117" data line was identical to the MTJ#3 data, except that the stellar data was adjusted to try and make it slightly more "realistic". It also removes some of the more egregious allegiance changes. (Basically, the Aslan and Vargr didn't make nearly the headway that was present by IE and MTJ#3.)
Of course none of the later changes really addressed the problem you are looking at. They also include a fairly obvious line error, some screwed up zone ratings, a couple wierd bases, and a few allegiance oddities.
As a result, the Spinward Marches has been published five times (six if you include GURPS Traveller's
Behind the Claw) and, really, none of them make much sense.
