Realistically I don't think there was much/any chance of avoiding this
problem. Despite many days of work trying to reproduce it by multiple
people, no one has managed even 1 single failure outside of the gate.
Even inside the gate it is hard to reproduce. I still have absolutely
no clue what is failing after days of investigation & debugging with
all the tricks I can think of, because as I say, it works perfectly
every time I try it, except in the gate where it is impossible to
debug it.
Regards,
Daniel
