Cannot Reproduce
Not a duplicate, is truncated in singleplayer.
Not a duplicate, only potatoes are affected when they are not rotated, they are dark unless rotated at 90 degrees clockwise.
EDIT: Never mind, it's early. Apparently, the potatoes BEGAN rotated in the item frame. I feel dumb right now.
@Ezekiel – Yes, this is still present in 1.6 and 1.6.1.
Please reopen, doesn't work even at correct orientation.
