What do you need to do for the Magellan achievement?

Question

I've explored the entire map. I've played an earth map, and circled the world in a sub. I've played a Pangaea and circled the globe by land. I can't think what else could be needed to accomplish this one.

Answer 1

The achievement is bugged. Look at this thread on GameFaqs to see the solution :)

Answer 2

Rather than having to go to another site for the solution, here it is.

To fix the Magellan achievement bug, navigate to your steamapps folder and drill down to:

steamapps\common\sid meier's civilization v\Assets\Gameplay\XML

Open GlobalDefines.xml in notepad

Find:

<Row Name="CIRCUMNAVIGATE_FREE_MOVES">
<Value>0</Value>
</Row>

Change the 0 in the tags to 1.
