Where is Jasmine Holiday?

@TillyLucker Jasmine only appears in the game during an active challenge. She was around during the Spring Plant Sims Challenge from about Easter to the beginning of May. But now that challenge is over. The sugar skulls were part of the challenge we had during Halloween. They won't summon Jasmine, but I do believe you can still make offerings with them at the graves of other sims and use the completed collection (which now has to be purchased in debug mode) to establish a friendship with Grim.
