Site keeps logging me out at Deck Builder

I want to save my decks to my profile, but every time I enter the Deck Builder it keeps telling me that I'm logged out and have to be logged in to do so, even though I logged in just moments ago. It seems like the Deck Builder doesn't register the fact that I'm logged into the site.

Hey!

Can you try clear your web browser cache. Once that is done, please manually log out of the site and back in and try again please.

...and that appears to have fixed it! Thanks!
