Okay so I've just looked back on the history of this ladder game between me and Hudsoncactus (Where I got totally pounded), and I noticed something odd about the picks. I had South Pole marked as my third pick, and Hudson had it as his fourth. One of his earlier picks had been taken by me (Jiangxi, his second pick and my first). Yet he got the territory, instead of him getting his fifth pick (Colombia).
By my understanding, he should have got Colombia and not the South Pole. Was that supposed to happen, or do they alternate (I got priority over his second pick, so he gets priority over his next one)?
I've never really payed much attention to that sort of thing before (Which is probably why I lose so many ladder games!), so I'm probably missing something obvious.
