Another thing that bugs me is that they add recipes later for master books that already existed, and I have no idea which master book unlocked some 1* or 2* master crafts.

Some friends ask me which one it comes from and i honestly have no idea. I just have them.

One of them swears he doesnt have the new 2* Crystal Glass ALC craft in his crafting log (he didn't have any of the previous ALC master books).

IMO they should add an extra line after "Quick synthesis unavailable" saying " Masterbook I recipe" or "Masterbook II recipe" just to make it clear from which book it comes from.
