Not really much of a problem, but I bought five blueprints in one transaction and right-clicked through them to learn them. Three of the recipes went into my character's crafting menu, the other two did not. All five were shown as purchased in the game log, three were shown as learned, and the other two simply disappeared. Was able to duplicate it one more time in three tries - seems to require very fast clicking (or at least very fast for slower hands that can't play RTS or twitch games
).
