I've seen logs suspended in midair when this happens (around 2-3 levels above ground). Can you check and see if this is happening?

When I've seen this behavior, I don't get logs suspended in midair - I don't get logs. What I do get is bizarre holes in the sky where parts of the tree used to be.

This may have happened to me as well, when you go investigate, the entire structure of the above ground tree appears as 'inside'.

This may also be related to bug 6704 that involves collapse notifications when entire trees cease to exist.

sorry about the delay.

No logs, midair or otherwise.

There are a few sky tiles where the top of the tree used to be which are black with '-' in either red or green. Is that what you mean by holes?

None of the former tree tiles list as 'inside' for me

I've gotten the collapse notification for some mined roots, and for some standard chopped down trees. It seems like the message pops up when the lowest trunk section is right next to lower ground (When I chop these trees down normally, some of logs fall an extra z-level to the ground and wind up at the bottom of the adjacent ramp)

Hey, this is kind of cool. :> But, yes, I can reproduce the bug as originally described. I have created a save file for convenience, though I don't think it is specific to any save file.

Debian Wheezy 7.5
uname -a:
Linux 3.2.0-4-amd64 <POUND>1 SMP Debian 3.2.57-3+deb7u2 x86_64 GNU/Linux

1) Fresh unpack of Dwarf Fortress 0.40.02 SDL from [^]
2) Fresh unpack of from [^]
3) Press ESC 3 times (to get past intro), then choose "Continue Playing."
4) Load region "bug6749"
5) Center on the miner.
6) Unpause, then watch as the root is dug out (already designated), then the entire tree vanishes, and the roots turn into Silty Clay Loam Wall!

Also, same results with Windows 7 Pro SP1 32bit, updates current.

also, when designating a ramp on a root tile, the tree also vanishes, but the floor between the tree and the ramp isn't removed.

I just saw this and wound up with "Snow covered Open Space" which is one of the more confusing things around. But it is rather annoying.
