[4.11P2 Prebuilt][Bug] HTML5 map downloading on the fly is broken. (Plus problems with non-map downloading on the fly on latest firefox)

An update on the not being able to resolve TappyChickenMap problem. I tried building and running a new HTML5 blank project with starter content using 4.11P2 and it works just fine. So this may be an issue with updating pre-4.11 game projects to 4.11.
