Hello everyone,
The following changes were made in a recent patch during this morning's maintenance. I want to apologize for not getting this notification up in a timely manner.

1. We fixed a bug where the Thanksgiving key could not open chests.
2. We fixed an exploit on Age 2 where people were able to get free amulets.
3. We made a rule change to the alliance join/drop system, adding a cooldown of 72 hours.

The third item in this list has generated some discussion. This change was made to address some strategies that utilized the lack of cooldown to perform some exploits. It will result in some changes, making cities easier to fight for, and will invite some changes to the alliance dynamic. We will be monitoring this closely, and may modify the rule in the future.

We are currently confirming and fixing these exploits as well.
