Sencha Cmd v3.0.0.250
Ext JS 4.1.3

After creating a new app using sencha generate app, images generated using sencha app build (or sencha ant build) are not being referenced properly by the CSS file. So for an app called MyApp, the images are being generated in build/MyApp/production/resources/images/default/, yet the references in the CSS files all point to build/MyApp/production/ext/resources/themes/images/default. Am I missing a configuration parameter somewhere?

Additionally, the documentation states that you can build the image slices using sencha theme build default. This unfortunately created a "resources" directory in /build/MyApp and not in /build/MyApp/production.
