surprised nobody has posted this. the "broken track" on EE was taken down and replaced about 2 - 3 weeks ago. for a few days the ride was operating without the track there. (here's a video of it without the track: Terrifying Expedition Everest Ride POV W Broken Track Missing! Animal Kingdom Walt Disney World - YouTube)
also the bird on a stick in that same scene is apparently back and working again and the prayer flags were replaced with new ones as well.
no Yeti news, sorry.
