So me and my friend we fighting a group of zombies and decided to give my strongest sword to so my fox can fight them, AFTER REALIZING IT WAS GONE I GAVE HIM ANOTHER SWORD AND IT ALSO DISSAPEARED, now my fox became my trash can eating everything i give him and not receiving it back.(killing the fox does not give your stuff back) and even giving them food does not swap the object, they also eat it, or keep it.
