Shadow Flips

Shadows flip in chests, inventory, etc...

What I expected to happen was...:

nothing

What actually happened was...:

Shadows fliped in storage when you put a chest in, but only the lines below, not in the same or above.

Steps to Reproduce:
1. Fill a contaner with BLOCKS
2. Put a chest anywhere in it.
3. Every block's shadow gets flipped in the lines below
