[Yes yes, I hearing Kovos thinking in the background "you're just now figuring that out?"]Anyway, I have a small farm in the second basement of my little house set up like this (Pic1). When I place a potato on one block (pic2, block under cursor), it makes the potato on that block and the two adjacent potatoes jump out. Also, on the third row, when I plant a watermelon anywhere but where the one is growing, it goes back into the ground. Same with the pumpkins on the fourth row. I tried disconnecting from the server, closing minecraft, and restarting and that did nothing to help. Bloodydiablo even tried to plant them himself and the same thing occured. We even tried breaking the blocks, replacing them, replowing, and the same thing occurred.
Any ideas as to what is causing it? Is it my setup or something?
