I don't know if this is really a bug but... If you leave the website logged in overnight (say the Rune Manager) the next day if you click things rather than being redirected to the login page since you've been logged out it just sits there spinning since it doesn't have the access. Even weirder is if you click "Add Battlegroup" it'll show the login page inside of what is normally the add battlegroup popup. You have to refresh the page to go and login (or open another page in the website). Again, not really a bug (maybe) but something that feels a little off.
This particular weirdness affects all of my computers so I don't think it's a session specific bug. I have cleared my cookies several times since this started a few years ago. I just saw it happen again and thought I'd put up a thread.
