My kids won't turn into doves.

I brought a prismatic shard to the witches shrine, it accepted and said "good bye Kim, goodbye Abel." (My kids names) and they didn't disappear. They are still in my house, they are still intractable. I can still look at their heart stats. So I did it again in a few game days. They still won't disappear.

 

This same exact thing happened to me just now. Weird enough, it got rid of one kid (still a baby) and kept my other kid in the house ( the one that walks around etc ) . Does it only work on children who are babies?

Even so... I still got the goodbye message for BOTH children . I DID want both children gone though so I want a refund!! xD
