Character steps in traps when using zone construction

Describe the bug

While using the zone construction task to dig deep pits, the character is happy to step into the deep pit it has just dug.

Steps to reproduce

Create a blueprint for a horizontal row of deep pits. Construct it from the zone activities menu.

I was standing north of the blue print when I began.

Expected behavior

The character should avoid dangerous terrain.
