I have noticed this the past few days. When I log on to the game, I can access the various quest lines. Once I either move away from the city page, to the map, for instance, or once I open another screen, like the Great Hall, the quest bars no longer open. I can see them; I can see that a quest has made progress (with the yellow exclamation mark) or was completed (with the green check mark), but when I click on the quest icon, it doesn't open. This is true regardless of the quest, whether it's an event, daily or regular. The whole section on the corner of the screen doesn't open. This occurs on the browser.
Once I refresh the screen with the browser, it will work until I once again click on another screen or feature, when it freezes up.
Reproduction steps:
Open and view a quest.
Go to another screen (map, Great Building)
Close screen and return to the main page
Attempt to open quest.
Refresh screen
Attempt to open quest -- success
Move to another screen
Attempt to open quest -- failure
This seems to happen only on zz
