In my v3 tamagotchi connexion, the matchmaker came out of the chest I bought in it's shop(I had a teenager)and took away all my food and happiness hearts.
Yes its normal. Whenm you buy the chest theres alot of things that can happen: POints Items and somtimes its changes you tamagotcfhi bak to a baby or an elder. But this is Temorarly. It wont stay like that. For instance: you have a girl right? Well the chest changed you tamagotchi from its stage to the Old lady.. which LOoks like the MAtch maker but isnt. Your tamagotchi does change back though. And the MAtchmaker doesnt come out of a chest.. thats what i know. at 3:00 P.M the matchmaker comes with a book.
