[ARCHIVED] [LD] Rebirth: Sims disappear off screen

I'm also having problems with Rebirth. My Sim completed their Life's Journey, getting the Burning Soul trait. I was excited to rebirth them in the Baleful Bog, but when I do, they stick around swimming in the bog aimlessly, and I can no longer control them. It doesn't even take me into CAS. When I go to Manage Worlds and go back into the household, the Sim turns into an infant and disappears forever. For context, I don't have any mods installed and I have all the packs, except for a few CAS kits. I even tried saving the Sim to the Gallery and trying in a different save but it doesn't work like it should.
