Summary0003468: Mining created obsidian pillars causes created floor above to crash down
DescriptionCovering magma with water will create pillars on the water level due to splashing magma.

Mining these pillars causes the floro above to fall down in a cavein.

There shouldnt be a floor above any more than a constructed pillar will cause a pseudo-floor.
Steps To ReproduceLocate a magma pipe.

Drill a hole from a aquifer or river source.

Allow the water to cover the pipe from one side, to allow the obsidian cover to attach to the side.

When water spills diagonally into the lava, a cave in occours. On some of these, the splashed magma will create a wall on the water level.

digg these walls to reproduce the cave-in.

The floor above is intentional, to keep items and creatures from falling into the pillar tile. You can use a channel or ramp designation to dig out the pillar (and floor above) without creating a cave-in. You can use an upstair or up/down-stair designation to mine out the pillar while leaving the floor above intact.
