I have the same.
Build menu; I get the tabs at the bottom, but there are no buildings above them.
Star menu; I get to open and see the tabs at the bottom, but its totally empty and I cannot change tabs.
Mail; can't open.
Chat; I have the box and the tabs. But they're all empty.
Generals; they are there, but click on one and I get a much smaller popup than normal, with nothing in it.
Advent calendar; can open the calendar window, all doors show as opened.
Quest book; Can open. Main quest tab is there and shows quests. All quests that aren't main quests are gone.
In sum; I cannot do anything, the game is completely broken. (I mean, even the merchant isn't working, so I can't even spend gems!)
