I found these not so well-placed objects in Boethiah's Spine Region:

• At Heleran's Lodge: The staircase (ex_t_stair_90_r_short) at (x,y,z) = (232006.625, 36788.934, 332.363) is placed and rotated such that there is a large gap between the top step and the platform, which looks weird and impractical.
• At Telvanni Library: There is a rock (terrain_rock_wg_10) at (x,y,z) = (232314.453, 51423.711, 757.662), which clips through the lowermost part of the entrance to the library.
• At (32, -2): A large rock (terrain_rock_wg_12) at (x,y,z) = (269041.844, -13588.843, 1176.417) is bleeding into a rope bridge by its eastern edge.
