I had a mela male of 19 years old named Joyful Darkness before death script on August 7th. He sadly died and I wanted to put him in my memorial. His page doesn't come up when I click his name in the sad news note, and his name doesn't come up on the add wolves in the memorial page. It's not a big problem I just wanted to put him in my memorial. He wasn't sold, free ranged, or even bred of my knowledge. And just in case I checked to see if I can get him back from free range but he doesn't pop up. If you'd like screenshots of the sad news note to see he definitely deceased I can post that too :)

Thank you to anyone who stated an answer or a similar problem!

If he had no living offspring, then you are only able to add him by the time of rollover for the following day. Meaning after late last night/early this morning at midnight would be too late.
