I created a new project and linked in the detached Central model. Then I acquired the coordinates from the link. All coordinates are correct except the Project Base Point elevation which is 1' high (-64'8" instead of -65'8").

Does anyone know why this would happen?

Note: The first time I thought it was because i hadn't copy monitored the level's yet and my existing level 1 was throwing it off somehow. I redid it, after copy monitoring the levels and deleting the existing template levels and the same thing happened again.
