I didn't know this, that's great news. Are they always going to keep clothes rotated 24 hours? I've been let down by my clothing choice two days in a row now (been level 20 since 3 days ago).
I guess they would start the 3-map rotation once they have unlocked 8-9 maps. That way, there would be 6 playable maps and 2-3 non-playable maps.
If nothing is available in the shop, order things through Spyke instead.
