We don't get told how many Ambulances to send! I am sending 1 per patient which is what I thought was required!
I had a.mission (Partial Building Colapse) to which there was 5 x patients so I sent 5 x Ambulances only to have another Ambulance requested because 2 x Ambulances are treating the SAME patient!
Is this a bug or is this supposed to happen again so need to send more than required??
