Goolean Update. Yes, I'm still working on this one. Replaced the CV3 boards in cars #2 and #3. With the new boards in, I was able to make the generators shut down properly when there is no demand in the building. Now the elevators will not respond to a Lobby Hall Call. If any of the 4 elevators are sitting at the lobby by themselves they will not open their door when the lobby hall button is pushed. Someone figured out by pulling the CV3 boards on cars 2 and 3 they could mask this problem. At least we're getting closer to the fix. I'll keep you updated.
