Yeah I felt it, hard to miss honestly. I was near the bottom of those stairs and it dropped noticeably colder than the rest of the room, not just a draft either, it felt more like a wall of cold air just sitting there. No windows nearby, no obvious source.
The Lemp history is so heavy that I wonder sometimes how much of what we feel there is genuine phenomena versus just our brains filling in the blanks because we know what happened in that building. But then again the cold spot was measurable, I had a basic thermometer on me and picked up a 4-5 degree difference over maybe a metre of space.
Did anyone actually get anything on camera or audio near that staircase? I've seen a few Lemp videos online but nothing that focuses on that specific spot. Curious whether its consistent across different visits or if it comes and goes.
