Corridor Parameters Reset Automatically When Opening Saved Drawing - C3D 2012

[Anonymous]

I recently added a new region to my corridor.  Everything works properly with this new region, however, when I save, close the drawing and then reopen the drawing, the corridor needs updated.  Upon updating, the corridor resets, and the parameters are also reset, to before the new region was added.

Also, in the same drawing but on a different corridor, I changed one of region's end stations.  Again, everything works properly with this new end station, but upon saving, closing and reopening, the end station is reset to the old end station.

The reason I need to get this fixed, is that upon saving, closing and reopening, my cross sections omit certain parts of the corridor's surface.  That is, there are "chunks" of pavement missing.  But once I rebuild, the cross sections show up fine; even though the problems mentioned above occur.

Any ideas?
