Summary0002785: Tree grows suddenly on top of constructed wall
DescriptionAfter building an outdoors wall, a full grown tree appeared on top of the finished wall.
Steps To Reproduce?
Additional InformationIt appeared there shortly after finishing the wall, so no muddying of that tile or something. It might have been that there was a sapling growing in the tile the wall was constructed in, but i am not sure on that. No other wall parts are affected

This would be a *really* useful thing to know how to do.

Same thing happens with stockpiles when you place them over saplings, wait long enough and when you remove it, some will instantly grow into trees.

I think this one is a holdover from 40D, its more of an odd thing than a bug, but its still a bug even if its a trivial one.

Well, the summary as changed by Footkerchief is not correct: I did not remove the wall! The tree grows one z level above, where before was open space and now is the area above the constructed wall. So it is like this (side view):

| tree
# wall

Ah, I misunderstood. What material was the wall made from? Did you do any modding?

The walls are made from slate blocks. And its pure vanilla DF.

I have been thinking, and it might have something to do with this: this particular piece of wall is build in a space that I have channeled out from the soil. So it might also be a tree that would have been growing in this tile before channeling. I have the save if it is needed, but I do not know if that helps.
