not at all- on mine, its been 5 days and i still have them- i might be able to figure out the problem because the name of your tama has a 10% chance of causing a glitch- i just need the tamas name.
Oh dont worry its completly normal! :kusatchi: When your parent leaves he/she takes some of the items away with it. Then the next generation also takes a few souvaniers from tamatown. But truth is you can always get 'em back. LOL hope i helped you
Well, the easy souveneirs to get like the arcade games will disapear because the games are so easy. The ring, crown, and cape will not ddisappear because they are hard to get.
