for me. I was out there much longer than you were. 2:53:11. Major screw ups on 2 and 3 even though I had visited both before.
I have yet to cleanly visit #2, even with distance to control enabled. Ribbon seems to have disappeared. A number of reentrants in the area, some with more veg leading me to think they are larger ones. My first visit to #3 I was one ridge over, but less than a minute lost. Solid since.
#2 ribbon is there. Unfortunately it took me almost 18 minutes to find it today.
OK, I got to the knoll, watch beeped, I looked around and didn't see it. Didn't spend time on it though...
