This was fixed in 4.6.1.

Thanks for the issue. It looks like you are trying to modify the baseHref of your application. Certain things like ionicons need to be served from the root in order to work properly.

If you would like to change your app’s routing structure, we recommend using the Angular Router to accomplish this, not a project/build configuration file.

I am going to close this as this is not an Ionic bug.

Thanks!
