Where is Jasmine Holiday?

I also am having problems finding her - or any version of her - I've look for days in every garden and I simply can not find any challenge coordinator - the closest person I found was a community gardener. I have NO mods in my game. My sims are level 9 and 10 gardeners, and I can not find this Jasmine Holiday or anyone of the challenge coordinator position (i understand she sometimes appears under a different name and age) please help
