What I expected to happen:
Using /clone /fill or /setblock will replace one block with Tie Entity (TE) for a new block with TE.

What did happened:
The Block was replaced and could be interacted with according to the new TE. However the previous/original textures of the block that was to be replaced would render.

Picture shows:
An ender chest replaced with a normal chest, yet the ender chest still displays.

Additional Info:
This happens with any TE so signs, skulls, trapped chest, banners so on. After logging out and back in the block will render correctly.
