EMS Rescue Clearing

Premium members get the auto-clear for non-needed EMS units. I've encountered an issue lately wherein that EMS Rescues count to deal with rescues, but will instantly clear if there is no patient to treat, even if a Rescue is needed on scene. I tried sending my rescue AAR, which kept picking the EMS rescue, and basically had to pick 2 rescues so it'd send a regular Heavy rescue. I don't want to disable the EMS send away, but it's basically a useless feature without this being fixed, because you can't use the EMS rescues (and we don't have fly-cars in my jurisdiction)
