unfinished ghost quest

[krecha_ae]

I accepted quest from science laboratory which respawns my dead sim. But now I have status "return to home to complete opportunity" - but I already am at home. The sim lives as ghost.
What can I do to complete this opportunity? Not cancel, but complete.

You can play as a ghost sim? Do you have supernatural expansion pack? If you do, you can change your sim back to a human. If you have a sim that master cooking and gardening skills, you can bring them back by cooking ambrosia. Go to the book store and purchase the recipe or you can google it.

Go back to the science laboratory then return home.
