Each item we get from the boxes, normally we can see on the steam inventory. Why this doesn't happen on this game? reference: https://imgur.com/a/jEVkP8C

Every crate I open, gives the same cat. New cat? Nah, as soon as you get a new cat, it switches straight to the one you already got

Do I just need to idle or clicking is necessary or gives anything at all other than a score?
