Please, please PLEASE tell me you had a "Zenith" weapon equipped and you weren't trying to farm atma with just your unupgraded Thyrus. Because you MUST have a Zenith weapon equipped or you simply cannot get Atma, RNG be damned.
Also you have to complete the unlock quest. I've seen so many people complain about not getting atma drops and they haven't even flagged the atma weapon quest!
