Dead sims are not greyed out in the relationship panel/Family tree

Hello everyone,

This is regarding the wishing well and rebirths. I had a sim wish for youth, but she was instead turned into a ghost. As a ghost, she was VERY close to being able to rebirth in the river thingy in Ravenwood, so I did a quick aspiration cheat and got her to be able to rebirth within a different household.

But even after about two weeks of sims days, the sim that got turned into a ghost and was re-birthed is still showing alive in the genealogy branch. The re-birthed child, whom had a stellar infant and toddler life because her skills were all maxed from my super duper legacy sim, is NOT glitchy, so that's good.

I don't understand why the OP sim is not shown as dead in the genealogy branch in my legacy sims. Is it stuck like that?

Thank you in advance!
