i tried a new fortress on 33e in a flat area with no slopes/cliffs. everything i dug was labeled above ground. some was light, some wasnt. but belowground crops were the issue and i couldnt get anything to be below ground. i tried building a house above the stairway both before and after digging. didnt make any difference. i tried constructed stairways instead of dug ones. didnt make a difference. i tried version 33d on the exact same spot, doing the exact same things. it worked just fine. i'm sticking to 33dd until this bug has been fixed.
and it definitely wasnt under a brook or any other water. though there is a brook on the map.
