Summary

0004260: Floor glitches occur when ice falls and melts in a cave-in

Description

When ice walls fall and smash, turning into water, a floor of ice is left above the place where the ice walls were when they landed, but the floor below them is destroyed, leaving an unwalkable area. (And also revealing walls below.) Apparently, ice that turns to water by smashing onto the floor is supposed to leave an area of ice floor behind, but it leaves the ice floor behind one Z-level higher up than it should. Or maybe this is just two different glitches, one that creates a magical gravity-defying floor of floating ice, and one that destroys the floor that the ice lands on.

Steps To Reproduce

1. Embark on a site with a glacier that is multiple Z-levels thick (because you need to leave a roof of ice over the place where the cave-in occurs).
2. Cause a cave-in where ice falls and lands on a stone floor, thus melting. I dropped a 6x6 area of ice that was only one Z-level thick.
This bug may be dependent on whether there was originally ice in the Z-level where the magical floating floor of ice forms. So don't dig the pit any deeper than necessary to get a stone floor.
