If I have learnt anything over the years it is that bugs are like onions, there are layers !
Each time you fix a problem and peel away a layer there is another bug that's been hidden waiting to cause more tears.

Trinity Net Nodes have an ID register, this has a format or rather had a format of Z,Y,X. The packet header used has X,Y,Z. The register has been updated and hey presto there are sensible transmissions.
Except that they are not. I seem to be getting stuff going in both directions. I think I know what it might be but I want to check.
As I say onions have layers.
