when it says beat 100 acre wood, does that mean beating all the minigames and missions, or just doing all the stuff without that and you should get it after the cut-scene with pooh asking Sora what he can do to make him stay in 100 acre wood with him? When it says goddess of fate cup, is it just completing it or doing the mission (you know like beating it with 8000 points or something)? I know that I'm missing one treasure chest in the world that never was so that might be it instead of 100 acre wood and i beat all the missions for nothing?
just go to youe journal, then go to missions...then scroll down to 100 acre wood
you need at least one orangeish King Mickey symbol for each mission and once you completed all missions, you will get Curaga and the orichalcum+
now you already said you have Curaga...so I know that you got the orichalcum+ from 100 Acre wood
just look at the 7 places I told you where you can get an orichalcum+ and see if you missed any.
