It appears that the work-around is to click on the tab 'Latest' at the top
This resets the cookie and it should all work OK
The problem appears to be the newly introduced 'Hottest' tab
Which means the other work-around is, just don't use the 'Hottest' tab, I don't
Perfect solution! Thank you darkspilver. I'll avoid the hottest from now on.
