I have a detailed grading plan that was working quite well. Pads, driveways, swales, retaining walls all defined with featurelines and added to the surface as breaklines. Architect decides to move some of the houses around, so I go about the business of moving the pads, driveways, swales, retaining walls to their new positions. All items relocated using grip edit are still working as breaklines. However, all items relocated using the Autocad Move command results in them no longer being used as breaklines. Trying to re-add them as breaklines results in the error message that they are already defined as breaklines in the surface.
So, short of removing all of the breakline sets with these items and then readding them, I see no way of getting these objects reassociated with the surface. Hopefully I'm missing something that one of you can point me to. I wouldn't worry too much about it, but there are 40 lots affected by this current change, with the likelyhood of more changes to come in the future very high.
Tested in C3D 2012 & 2015 with identical results.

Have you tried deleting the feature, using the oops command, and re-adding them as breaklines to the surface?
Jeff,
One more thing to try before you say uncle...
On the definition tab of the Surface properties, UNCHECK these breakline additions (in fact, I'd probably uncheck them all to be safe), apply and let it rebuild the surface. Now turn the check boxes back on and let it rebuild the surface again.
I've had that fix some strange anomolies in the past so maybe it would work for you too.
EDIT: The idea is that you're rebuilding the surface WITHOUT the breaklines (very much the same as deleting them from the surface) and then rebuilding it with them again. Hopefully that will cause C3D to read the breaklines again.

When you moved the Feature lines with the Move comand did you hold z constant from base point to destination point?
I think you recall the old warnings in the best practices manual regarding the move command so I might just chalk it up to that if the delta z did not = 0 through the move.
I would give the oos thing a shot. Works great.

Thanks Don & John, too! Don, the unchecking/checking was a good thought, and I had thought of that as well....no go. I ended up using the Erase/OOPS/re-add breaklines method. Worked just fine.
John, as for the old Move issues, I've been using move with featurelines since sometime after installing C3D2012 and hadn't noticed any issues with it. I know that earlier versions really took exception to this, but this is the first time I've seen something that MAY have been caused by doing so. As I noted, some of the breaklines which no longer worked were not edited, via either move or grip edit, they just happened to be in the same breakline set as those that were edited.
