Anyone get the sap and look behind the tree and notice Oblivion? There it is, an endless Oblivion. There's a chest to the back of the tree, all the way to the left. Beyond that looks like a template they either forget to build or block off with the back of the cave. I made sure I had a save and went to explore it and fell into a blue hole and couldn't move. Kinda took away from the immersion of the beautiful cave that's for sure.
***edit***
I'm not complaining BTW. I'm used to Skyrim being full of bugs and I don't expect to have near as much fun as I had originally planned with this game. When you don't have high hopes the fall isn't that hard.
