I actually think melian1965 isn't really talking about the doctors not doing anything, nor the patients and/or doctors being stuck in the hospital. I think melian1965 is referring to path problems (I don't remember what the game designers actually call it, but it has to do with where they can and cannot walk) in that they get stuck and start walking in circles. In other words, the builders act like they are trying to get to the front of the building, but can't. The kids near the black vines or the doctor near the black vine seems to get stuck, same with the red flower in the bottom right hand corner. Is that what you meant? I have seen another reference to the problem and one of the game designers responded back that they were aware of it and were working on a solution.
