0003905: Ice's Effect on Subterranean/Above Ground Irregular
If a tile is dug out while a tile of Ice exists above it, the tile is Subterranean (at least until that ice is dug out), but if the tile is dug out first and then the ice forms, the tile is Above Ground. It is possible, in four Z-levels, to have a subterranean tile with above ground Open Space above it, which doesn't make much sense.
1. Dig a pit.
2. Let ice flow in to cap off the pit.
3. Dig the pit deeper.

The areas of the pit that were dug before the ice lid was formed will be Above Ground, while the areas that were dug after will be Subterranean - even if they have above ground "open space" above them.
No tags attached.
