I can't build any buildings anymore.
When I select a building to build I can place it on the ground, but if I click on the "Confirm" button, the "Confirm" and "Cancel" buttons disappear, but nothing happens.
In my browser console I see the following error:
not down
script.js:16871 Uncaught ReferenceError: building is not defined
at engageBuildingQueue (script.js:16871)
