Pistons bases have a double texture

This is an old bug, so I don't know whether it is fixed or not, and it is on a free beta version (which I have no idea of). Piston bases (the ones that don't move on pistons) are shifted back and have the head texture on it. I don't know which side it should be facing, (north, south, east, and/or west) but I hopefully see that the bug is fixed.
