Summary0010214: Objects Dropped Through Floors Due to Tree Fire Related Collapses floating in "Open Space" tile
DescriptionAfter having a massive fire break out in the forest on the surface of Hammeronslaught (cause unknown) several trees collapses and their limbs broke through multiple z-levels of the fortress. Objects that the collapse collided with that were in stockpiles didn't take damage, but they are now permanently glued to the location they ended up in. In addition, the floor tiles they are on are now also immovable, and do not collapse when channeling completely around them.
Steps To Reproduce1. Dig a fort beneath several trees
2. Designate and fill stockpiles in z-levels directly beneath trees
3. Light trees on fire
4. Watch as tree limbs collapse and break through multiple z-levels, destroying everything in their path
5. Observe the final resting location of your now immovable items
6. Requisition unstoppable force

This can be seen in several locations, but I have surrounded one of the instances on z-7 with microcline floors to make it stand out.

I have an additional save just prior to the fire if desired.

Using LNP 0.43.05-r2

There are also two instances of immovable object stacks near the SSW most pond on z-0. Unknown if they're related.

Your objects are floating in an "Open Space" tile (shown at the bottom of the list when you loo[k] at the tile); dwarves cannot enter the tile to retrieve them. As a workaround, building a wall on the z-level below will provide a floor for access to the items.

Thanks Loci! I hadn't even considered it - for some reason the idea that the items themselves were floating hadn't occurred to me. I'll give that a shot!
