On the desktop page for Boardgames (https://paizo.com/boardgames) there's a link to "Level 20". When clicking on it, it forces a login, then endlessly refreshes. I can't find any Product Discussion forum for it, so looks like it's not just me. It's the same on a phone, when using "Desktop Site" - but I can't otherwise locate 'Level 20'.
Also couldn't locate under "Gale Force 9" which appears to be the producer.
Working now.
