Where is my Stone Chest Recipe? (Solved)

[Shadow Locust]

I finished the quest and still can't see any Stone Chest in my crafting tab.
What happened?

Edit: Ok...it seems the wiki of the game is missing information that the Recipe is given by mail in the next day. It would help a lot some new players if someone add this information there.

[I Kinda Fail]

I mean... this is only an issue if you use the wiki, to be fair? You wouldn't even know the quest gave a recipe for completing it, unless you read the wiki beforehand. It would just be an "Oh, cool!" moment the next day when you get your reward.

I think most of those special bulletins act that way, though. Either a letter or a cutscene give the "true" reward. (Pam's quest, for example, has no reward until you watch the cutscene, THEN she mails you the letter, I think?)
