Female Horse disappeared after breeding

Hello, this is my first time breeding a horse and i might have done something wrong. As breeding completed i collected the male (t4) from the breeding market but it still has breeding count 1, the female (t7) has disappeared and no offspring has been generated. Where did i mess up? Is there any chance to get back my t7 female?

 

well, my horse also disappeared while training skill on the stable... i think cause by the new update
