Crafting Bug

I recently crafted Taliyah i didnt check my champion pool after that because i thought it will just be there when i will need her. I hopped into ranked and to my suprise i couldnt find her in champ select i thought that it was a bug but after i finished the game i went to look for her in my unlocked champs and she wasn't there. Iss there any possible way to get her back ? I think that Riot has to keep some logs of our crafting and will be able to bring back my champ (?)
