I've been having this problem fairly consistently. I click on "Initial Draft" and the page cycles through loading but I get a blank screen with the Sandbox banner. Usually when I click it again, I get the page to come up. This happens about half the time I try to navigate through the site. But I was trying to respond to a trade request by looking at another roster and I cannot get the page to load. I open up "Standings" and go to the team I want to check out and click on it...blank screen...repeat x20...blank screen. I switch leagues and go to my other team and try it...no issue, opponent's roster opens right up.
This is with my OKC team. My CDA team looks like it works fine (or at least works eventually).
Thanks!
