I have a dropper (or dispenser) placed with a particular orientation; the "hole" is facing down, toward the ground. In 1.7.9, the item gets pushed out downward, through the hole. However, in 14w18a, the item gets pushed out of the SIDE of the dropper (or dispenser), even if the dropper (or dispenser) is surrounded by solid blocks.

It seems to be random which side it comes out. If one side is not covered by a solid block, then the item will come out that side.

Hope this helps! Please fix this bug! I need both a working dropper/dispenser PLUS working /clone and/or /setblock commands for a map I'm making... and the "RESET" function has to put the blocks back into place.
