Yep. I talked to Rob V and he did indeed edit the courses and removed some "extra, unnecessary" controls... without realising that what was two good legs was now a single not so a good leg. So kind of accidental.
The annoying thing is he didn't even do it to save putting out (& bringing in) controls - in some cases the control he removed was still being used by other courses.
Quis custodiet ipsos custodes?
OK, well that explains it.
