First rule of Minecraft: don’t dig straight down.
When deconstructing a building that has a sizable overhang, such as a bridge, Hearthlings will frequently remove the block directly beneath their feet, causing them to fall off the building.
Steps to reproduce:
- Build the bridge stair segment template (link above), positioned out over water.
- Once complete, order it to be deconstructed.
- Observe Hearthlings start to resemble lemmings as they leap into the sea.
A deconstruction which went roughly in reverse of how the building was constructed, without Hearthlings choosing to remove the block under their feet and falling.
