Extended Pistons Have No Bottom Texture on The Extender for The Piston Head

The whole bottom part of the bar on the extended piston is invisible. It's not a huge bug but I think it should be fixed. With this description I have a photo in game. Thank You!

p.s. This bug doesn't happen that often. On some pistons its just normal. 😛
