Don't know if anyone has posted this. But I have come across a bug in my single player survival game where there are very straight lines dividing things, like there was sand and it had a straight edge then a 5 block drop to the ocean. The trees along this line where trimmed to fit it as well.
I will have to get pictures. This also showed up on the map I crafted.
