I don't think you'll notice it in the thread, so I'll leave you a message here:
1. Quest 2 for the Ifrit Gauntlet was already claimed months ago, by me :\ You can only choose from the two remaining quests: 11 and 12, so hopefully you didn't actually start playing it yet otherwise you'll have to start all over.
2. Quest 5 for the Shiva Gauntlet was claimed 3 posts before you by E.J., so you have to wait until Sham makes more quests.
The lesson of the day? READ.
