Do cloak blueprints appear at random?
My first playthrough, I got the blueprints for all cloaks, but I never had enough butterflies to buy them all.
Now on my collect-everything playthrough, I have all butterflies and hundreds of credits, but only the pattern for the sprite cloak. I've been trying to open every chest this whole time, because I knew I'd have to pay for the cloaks... I just never got the blueprints for them. And I've opened nearly every chest in the game.
Did I just forget and miss the specific chests that have cloaks in them, or is it random whether you get a cloak on your first try or your last?
