Zone field not clearing

[SandwichPie]

Describe the bug

When making a new zone, it appears to be theoretically possible for the visual indicator for the field to stay drawn, and persist even when the zone is removed or the game is restarted.

See attached a screenshot of the game after the zone had been removed, and I'm in the examine mode.

Steps to reproduce

I'm not entirely sure how to reproduce this reliably. It happened directly after the confirmation prompt for creating a new zone, as normal. My best guess as to how this happened was I pressed too many keys, and buffered an input into the curses prompt before it was finished.

Expected behavior

The field for the zone will be permanent, and always render itself.
