I can confirm this, we just rode EE a couple of hours ago and the entire scene is completely dark. There was something blocking the yeti but the scene was too dark to even tell whether it was a tarp, a rock, or what. The only indication that there was supposed to be something there is the sound effects are still on, however they are turned waaaaay down. But it could be the speakers are just muted by whatever they are using to block the scene.
While it bugged me my daughter couldn't see the yeti, I was rather excited to see they finally are doing something to fix it.:sohappy:
