leveling them up gives no missions at all. I'm level 7 or 8 on all of them but I get no missions like I have from the other swap force characters that can be won via spinning or gems. Is this because the dark variants are not technically selectable in the game (you have to download them from the Bluetooth portal) so maybe the devs haven't finished the code for that part yet? Kind of disappointing since I get at least 5-10 gems per skylander from all the missions. Oh well, I was just hoping for special missions since they are dark. Hopefully the devs give us a dark house that only they can use then I wouldn't care about the missions (they can just change the Legendary house black and I'd be ok with that).
The dark skylanders that were added in this update now have missions so I assume all variants suffering from no missions will get them once officially available to own by spinning/gems.
