I put a clinic patient in the lab for blood work. I ran out of energy, so i left game and came back to it later. My patient is still sitting in the lab with a big "!" over his head, but when i click on him its not doing anything.
If there are any further problems, there should be a thread on the Bugs Forum that will get your issue noticed more quickly, although we are aware of this problem. If it is not working correctly for you now, there should be a fix shortly. Thank you for your patience.
