Actually, to reproduce this bug, simply access the members section. If it goes to a black window, which then displays a log in screen, the bug has not happened on your machine. If it does not, and leads to another section of the site, which states that you are at that page due to not being able to run Signed Java Applets, you've experienced the bug. At that page, the game can be accessed, but only in a low detail version. Attached is my copy of the bug, I have one very similar. Hopefully it helps.
