Devil and everyone:
It looks like we'll be using blksea terrain and not blkseaw (assuming AH3 comes out before June).
That means the ground won't be white, so we probably wouldn't use the winter skins.
Terrains need to be converted to AH3, which is a lot of work with only Ghostdancer heroically working on it himself currently. By June, converted blksea and blkseaw will be available, but because of needing new custom tiles for winter, blkseaw won't have trees at first.
