Sorry about being a couple of weeks late on this, but the weapon quests got changed a while back, when you start them, Nuru will send you to an arena with some minibosses, kill them and talk to SAIL and you'll get the recipes and enough of the class crafting material to make the 1st class weapon.

If you haven't done the vanilla arena missions, she might give you two "Travel to the arena?" prompts at once, so check you're going to the right one.

Also, the things being open isn't a bug, the outpost is tracked per universe and not per character, so if he's already opened everything on one of his characters, anyone playing in his universe will be able to use them too.

Oh alright, thank you!
