I think I located the bug that causes the load issue (black loading screen never refreshes).

It's caused from a bug in chrome, there is an easy work around on the server side, not the client side however. The bug is documented at: https://bugs.webkit.org/show_bug.cgi?id=30862

The easiest way to fix it is to append a rev # to all pages, this forces chrome to request a new file and ignore cache.

Example, right now you load: play.casinorpg.com/game.js

you should load: play.casinorpg.com/game.js?rev=2013042701

The server identifies as the normal game.js script and sends that to the client. The client then caches game.js?rev=2013042701 so if you do another update you send it as game.js?rev=2013042702 and since the client cache does not have this cached, it sends a new one.

The rev ID I used is just YYYYMMDD## which is a common scheme I use, you could use whatever you want as it always increments with each update.
