Moving blocks (being moved by a Mechanical Piston, rotated by a Mechanical Bearing, etc.) can't be collided with.

This has been reported before and all of it has been due to Optifine, since Optifine changes the way collisions and entities work
Huh, well I guess the problem's going to have to stay, because I can't run Minecraft without Optifine.
