This should have one of the mandated Elf&Safety warnings attached.
There is one helluva risk involved in trying to out how these things are routed, re routed,etc.
Some of the these errors may cause packages caught up in these C.J. to be ground down to dust by the wear and tear they get.
Sometimes the code gets misread and that package will do the Bermuda Triangle holiday tour for all the time this planet has left.
Play it safe..... assign blame to Horseshoe, pour a drink, light up a cigar, repeat as often as required until all traces of this(and with luck of you know who) have been scrubbed from your memory.
Then have at least one more drink...and hie on over to the PWI thread.
