Treasures Not Collecting Properly.

[UltimateZob]

For some reason, some treasures are collectable , but some are not.  Whenever I go up to a treasure, it will play the music and zoom in like it's supposed to, but it won't show up in my inventory.

I have collected these treasures without any issue:
Jelly Beacon
Krotite Armor
Crab Armor
Mithalas Pot
Arnassi Armor
Mithalas Armor
Mithalas Doll
Seed Bag

However, these treasures refuse to show up in my inventory:
Urchin Costume
Jelly Costume
Mithalan Dress
Glowing Seed

Is there any sort of solution to this problem?  I honestly don't really care about not being able to get some of the purely decorative treasures, but it irks me a little that I'm not able to use the abilities of two of the suits.

This may be stupid, but you've checked that these treasures aren't on one of the other pages of the treasure menu?

I am a moron.

Thank you, Xiagan.  That fixes my "problem".

Glad it helped. Don't feel bad, you aren't the first with this "problem".
