Why sometimes when I go to a habitat/animal/habitatobject by going to the main overview, in the CALL STAFF subsection, sometimes I find written for example "Assigned Keeper" with a telephone symbol (and if I highlight it I get written Call a keeper URGENTLY), a sometimes instead (in another habitat but in the same area, therefore with the same staff) I find "Call Guardian" written with a telephone symbol (and if I highlight it, Call guardian appears written in the habitat), and in both these cases I choose to call guardian "Custodian Assigned urgently" appears... While other times I only find the option Custodian Requested without the telephone symbol (if I highlight it, it appears as Call a caretaker URGENTLY), and in this case if I make this choice everything remains unchanged (and not so can we understand if he really called staff or not)? I would like to point out that this difference occurs with both caretakers, mechanics and veterinarians, in different ways albeit in the same area.
