Ok, then I guess there is a profound difference between ghost babies and real ghosts. Can you please reiterate clearly what you are trying to do?
My ghost baby (grown up now) ate ambrosia and just got her day counter reset to the beginning of the current phase.
dont know about ghost babies but this is what im trying to do.
- my sim died of hunger
- got urn, planted the urn in my garden -> becomes a tomb.
- family went on with life.
- after a while i got 10 in cooking and fishing, so i can make ambrosia now.
now this is the part that i cant get to happen -> revive the ghost sim/get her to eat the ambrosia.
if you took the urn (not the tomb) to the science lab, you can play as the ghost sim -> make her eat ambrosia = alive again!
but i tried taking the tomb with me to work as a lvl 10 science job -> nothing happened :/ cant bring her back?? -> cant eat ambrosia = cant come back alive.
