Despite best efforts of Ewen Rennie and me, control 121 (used on the Blue and Brown courses) was on the wrong boulder. The nature of the terrain near that control meant this caused no significant issues except in the head of one person. To appease I have voided the time for the relevant leg into that control on the Blue and Brown courses. It made absolutely no difference to the winners or leading positions on either course. Apologies to Margit Matthews, who was given a dead brikke. There was nothing I could do to find out any of her times, so I had to leave her as mp. I was also asked to recheck Dillon Thomson's result as he was sure he'd not missed a control. Unfortunately, he made a mistake and one of the controls he punched was from another course.
