TamaTown tries their best to make the games on Tamatown to get the souveneirs as easy as they can, because some Tama owners are about 6 years old or something like that. But sometimes theres a bug on tamatown for me, like this one, too
The same for my V4. It is not a glitch, it is just the way things work. The only ones you get to keep are posters and items from plane trips. I mean, would you really want your parents graduation cap? Or colouring book? (These are V4 sovineres.) I didn't think so.
