Whims won’t delete. Only two whims at a time. Cannot ignore whim.

@martyrandroid Whims have been replaced by wants/fears about 3 weeks ago. Is that what you mean ?

You cannot delete the new wants. That's not a bug.

They re-roll when your Sims sleeps though and there's a potion if you want to get rid of them

Not sure that's what you're referring to though as you said you had this even before they introduced wants/fears
