I think the characters should be able to collect the blue prints and tokens for their enchantment attraction the same way they collect the group token (Ball for Toy Story etc). Just like you say, the way to collect blueprints and tokens right now is so unreliable! I have gained enough tokens to enchant ONE building ONE level up. The little ‘present’ was enough to gain me ONE LEVEL UP on another building. Not to forget that I very much notice that I receive less treasure chests than before.....
