currently, the "Slurred Speech" missions seems to not be functioning correctly.
I'll dispatch required units (ie something to treat the patient) and then transport said patient afterwards if required. However the mission remains and it requires "Any vehicle" to attend which will then instantly clear the mission instead of the mission clearing after the patient has been treated. (Its also possible the patient is being treated and then the ambulance is auto-standing down, but im not sure and the mission should still be clearing)
I've had this occur a number of times now, all with the same mission
