My Angelgotchi just died.. What happened?

Okay, so I had a Pakuten that was 6 days old. I happened to stare at my Pakuten when it just suddenly got sick! I used the bow and arrow to cure it... The first dose didn't work so I tried again and the seconds dose didn't work. After giving it 6 doses in total, it still didn't work! Then, I got the evolving screen and saw it turn into a Deburitchi!! It flashed to a Deburitchi and then back to the Pakuten for about 10 seconds beforeit finally stayed on the Deburitchi! 20 seconds later I was pressing on the buttons to get the icons to flash up but then it reset to the hatching screen where I hatched up a new angel! What just happened!!? Awww, I'm going to miss my poor Pakuten :<

Debirutchi is basically the worst-care character; which means it was badly neglected.

Once it evolves into Debirutchi, the icons will no longer be accessible and you will need to reset to start over.

Oh! U~U

I will take better care of my Angelgotchi in the holidays, thanks!
