Yeah I felt it, couldn't believe how sharp and localised it was. Not like a draught at all, more like stepping into a refrigerator and then stepping straight back out again within the space of two or three paces. My mate thought I was imagining it until he walked through the same spot.
What floor were you on when you noticed it? We picked it up on the fourth near the top of the staircase and I've been wondering if other people are reporting the same area or whether it's moving around the building. I've encountered cold spots at a few locations on Dartmoor but nothing that distinct and that contained.
Did anyone have a thermometer on them? We had a basic digital one and clocked about a 6 degree drop but I wish we'd had something more reliable. Would love to know if anyone got proper readings.
