The polygons property was missing from pixiTextureByName at this point:

airmash-frontend/src/js/Graphics.js

Lines 195 to 198 in b7c4120

	var initPolygonsScale = function() {
	pixiTextureByName.polygons.scale.x = game.scale,
	pixiTextureByName.polygons.scale.y = game.scale
	};

The call stack above indicates this function was called from resizeRenderer:

airmash-frontend/src/js/Graphics.js

Line 118 in b7c4120

initPolygonsScale(),

Likely root cause is that assets/map.json had not been fetched yet (or at all) at that point:

airmash-frontend/src/js/Graphics.js

Lines 200 to 202 in b7c4120

	var createMapFromJson = function() {
	$.getJSON("assets/map.json", function(mapResponse) {
	pixiTextureByName.polygons = new PIXI.Graphics,
