These achievements are known to be broken. Before reporting a broken achievement, check the achievement's page to confirm that you are meeting the correct requirements.
- Connoisseur - Does not work as of June 2012. This achievement is no longer listed and cannot be earned.
- Magellan - This is often reported as a broken achievement. Some people have had no problems unlocking it (I have confirmed that it will unlock -Ragan651). Others have had to modify game files to make it work.
Broken in Gods and KingsEdit
- Kamikaze Attack - This achievement requires you to have a unit with 1 HP. This was intended for the original version, where units had 10 HP. With Gods and Kings, units have 100 HP, and 1 HP is less likely to happen. That means this is a very difficult achievement to earn with the expansion.
- Barbary Pirate - This achievement cannot be earned with Gods and Kings. Disable the expansion to unlock this.
Broken in Brave New WorldEdit
- Diplomacy by Other Means - Autocracy is no longer a policy track. Disable Brave New World to unlock this.
- Freedom Isn't Free - Freedom is no longer a policy track. Disable Brave New World to unlock this.
- Model of a Modern Major-General - The Foreign Legion is no longer counted in Brave New World. You need to disable the expansion to earn this.
- With an Iron Fist - Order is no longer a policy track. Disable Brave New World to unlock this.
- The Wonder Years - The United Nations cannot be built if Brave New World is enabled.
