I am playing the Chrizmantv campaign and every so often, it says there's an error and the cardio is always affected. It's like the patient gets stuck on the machine and it looks like there are 2 machines on top of one another. It is annoying, because even though i then set the queue size for this room to zero, patients still queue for cardio and a doctor goes in the room. How can I sort this out?
