I should have looked closer at the transformation in the minimal example. It was hard to see anything in the original problem, but I really ought to have spotted the issue here... Thanks.</p> <p>Thanks Joe, oh that was rather simple, your answer comes just on time before I set off on the wrong path. I should have looked closer at the transformation in the minimal example.
