What I expected to happen was...:
Be like the PC version with not bugged fences.

What actually happened was...:
The bottoms of connected fences are black or shaded, as in the picture.
*The circled fences in the picture are the bugged fences.

Steps to Reproduce:
1. Connect two fences
2. Dig or look up to see if it is black on the bottom (may need to try a couple times)
3. It is a bugged fence glitch.
