So here’s the problem book 2 of PoD lists Tech world and Drinax as both being TL F but the Traveller map list both as TL E. Now I can accept this because I consider the Traveller map to be largely a RP Tool minor variation is just error in the data. Now we know that this is wrong in Drinax case because it’s current TL is closer to 0 (TL being infrastructure and Drinax doesn’t have any) and before the bombing it was F because the Harrier is TL F. This is were borderland causes issues Tech World is listed in borderland as TL E that means the only place where the Harrier can get repaired is Theev which is 11 jumps away from Drinax. I feel this is another case where mongoose is failing to keep thing consistent.
