I am trying out the caves beta and have been observing the updates to my old world seed and a newly generated one. In both instances I am finding more extreme terrain transitions, especially with the mountain. I've been able to nearly touch the boughs of Yggdrasil (touch the skybox) with how high and steep these are getting. It would be cool expect for the common occurrence of entire blank cliff faces that ascend into the heavens. A flat sheet of grey barren of any rocks that do not appear natural. It is nearly there though, the climb up to the skybox was exhilarating and had a few neat towers along the way. But if 1 out of 4 faces of the mountain is barren, then something did not compute right.

PS. "I've been to the top of the mountain! And I'm going back!" I am gonna reach the boughs and prepare for war with the sky.
