I lost Deva's tears?

[Skurzaków ksobnych demaskujemy]

I bought all the stuff from the Vrischika's shop before starting Eccos quest. I gave her the Fiend's Tongue and after that she asks me for Deva's tears and to my surprise they aren't im ny eq 0.o . I'm almost sure I havent sold them or dropped them so I have no idea. A bug maybe? Is there any way to get them? Even like using a console command or something of that sort?
