When i place a sand block directly above an Oyster the Sand drops down and breaks the Oyster. Two Oysters are dropped instead of one. If Sand is placed more than one block above the Oyster then the Sand breaks just like dropping it on a Torch.

I am playing the latest Agrarian Skies Mod pack on 1.6.X and i could not find the Version of Mariculture that it uses.

Fixed in 1.2.2
