Corridor frequency changing when opening 2014 file in 2015?

[CADvisers]

Anyone experiencing something similar?  Same file in 2014 and then opening in 2015.

Is that happening in the curves only? Civil 3d 2015 has new frequency options in curves.

No, the interesting thing is that there are two corridors in the drawing.  One that has curves and tangents results correctly.

The one with an issue is only a straight tangent.  Which also puts a twist on this.  Only one of the corridors has a problem.

If a new one is created in the same drawing, using the same alignment, the same assemblies and same regions, it all is fine.

The bottom line is something is happening when opening the file in 2015 that it shouldn't be doing.
