Nero's fire
Warlord
As long as we are on HN units, I have noticed a few times that pirates have been attacking my garrisoned troops in cities.
Yup this happened to me in vanilla a few times and from the same thing, trading maps.
In three different 0.23 games now, I have gotten the "you have circumnavigated the globe!" message and reward (+1 movement of ships) when I have clearly not circumnavigated the globe. It may be tied into swapping world maps with an AI who has mostly circumnavigated, thus providing me with a world map that has a clear circumnavigation path -- but I could be wrong about that. ..fritz..
