Pouster, send us a cutdown design that is showing the same fault.

In doing this, you will get a number of outcomes.
The first is you discover your fault and now know how to correct it.
You discover a Xara fault that you can advise on.
You get the same fault that we can look at.

Anything else will be guessing unless someone has overcome the self-same problem before.
