Rode today:
-no steam at load
-no waterfalls, though possibly because of cold weather?
-bird was working
-Yeti was clearly visable, illuminated in red in addition to the strobes.
The Yeti not moving honestly does not hinder my enjoyment of the ride, however, it would be nice if they restored some movement so it doesn't look like a statue.
Also, I gotta question why this thread is still stickied, as its clear that besides the Yeti, all the other effects come and go regularly, and you could say the same thing for every single ride at WDW (sadly, given the current state of maintenance at WDW)
