Christmas Event Bugs

Now I cannot log in! It gave me session timeout immediately after log-on!

..

i cant get in ? it say maintaince i about to start and it return to main page !!!

without Event Calendar it looks work normally... i have 90 presents... and it goes forward without frozen/emtpy windows...

Same here star is completely empty, can't do quests, can't pull up chat window, can't expand options dropdown, roll over friends at the bottom and they disappear - jeez don't you guys test anything before you release it?
This game is rapidly turning into a farce - BB why don't you just pull the plug?

Opened the advent calendar and found all doors open, after that quest book and chat tabs unresponsive.

same here. as soon as i open the advent calendar the game breaks. the animation becomes very juddery and none of the menu's work, the star menu is empty, can't select anything

Servers going down messages.

Bit worrying, just got the problem by visiting someone else's Island then going back. Didn't access the calendar.

Another wasted evening trying to play after start of event. Can't do anything on the home island, not even send out explorers.
They better not make us pay for opening missed advent calendar windows.

I should also point out that the bug is triggered by returning to the home island from an adventure, was only able to test this once before the hotfix started.
