I've found the issue is typically the corridor doesn't match up with another surface correctly and you need to adjust the regions station parameters by a hundreth or so. That usually fixes the problem.

A bit ironic how i am trying to furiously fix the same problem on my 2013 C3D seven years later. I dont even understand if its a bug or is just something i am doing wrong.
I am also getting this error in Civil 3D 2015..
It seems that there is an explanation by Autodesk:
but the given solutions don´t solve mi issue.
Hi.
Yes, each pasted surface is a corridor surface.
I saw that it depends of the order of pasting surfaces.
My work around is:
-paste a corridor surface.
-save the drawing file with a new name.
-call the "recover" command with the new file to see if the surface is damaged.
**I saw that sometimes you can paste correctly the surface but then without getting the error message but then, when you call "recover" command it says that the surface is damaged (and some triangles are out of the properly boundary surface).
I write in a paper the properly order to copy corridor surfaces, if some of them throw the error message, then I try to paste it before or after of another pasted surface.
I had a corridor surface (only a ditch) with a geometry in plant "V" between 2 alignments, and I had to paste previously that corridor surface before the 2 corridor surfaces.
