Why did my hostile unit wont die

my hostile unit wont die and its health bar is 0 idk what happened i checked scripts and i dont know which script it is and i checked units theres nothing so idk

Did you check to make sure the scripts for the hostile unit have triggers?

Did you add a death script?

did you if not its simple to make just do when unit arrtibute becomes 0 or less if trigering attrabute=health then do destroy owner of trigering unit if you want then you can do send chat message Name of animal has died
