I'm still confused
. The first time I logged in today, I got a patch notice exactly like the one grimsoul posted in his original post. I was leery, having read this thread. I clicked on the "See Patch Notes" link and noticed that a new tab opened, but it did not have a title. I clicked on "No" and the tab went away along with the patch message. I was able to log in as if none of this had happened.
I've since exited and re-entered the game several times and have never again been asked if I want to download the patch. Not one to look for trouble, I've just let it slide.
Of course, we have a new Challenge starting in a few days. I suppose if this is a real patch, I'll have to search for and download it, but for now, at least, it is as if it never happened. Maybe it was a mistake and has since been taken down?
