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. It's still possible however, just highly unlikely. However, it does work when you defeat the enemy unit while defending, which increases your chances somewhat.
- 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.
