I have to agree with the elevator issue. I have 7 elevators per floor, and my hotel is not gaining any revenue so I cannot keep up with expanding my property. It would be nice to not have to worry about so many elevator issues.
I would love to be able to walk away from whatever I am fighting and heal a bit and return and have the monster have the same HP as it did when I walked away (or at the least only heal in small amounts same as we do), instead of resetting itself entirely and having to start the kill over.
