Point Features at Elevation Grid Cell Centers

Hello,
I created Point Features at Elevation Grid Cell Centers for a DEM, and edited the elevation for many point features. As there was an overlay identified in the Overlay Control Center, and I had saved my GM session, I exited GM without created a new DEM based on the revised point feature elevations. When I came back into GM, the point features overlay was not available, and I couldn't find a file anywhere in the working directory. Is there a way to make the overlay that is created through the Create Point Features at Elevation Grid Cell Centers a "saved" overlay that is available for follow-up work sessions?
Thanks.

Any created point or terrain layers should save right in the workspace file itself. They aren't in any other external files unless you export to a a file in a specific format. If you saved a workspace after creating them then if you load the workspace they should be back.

That's what I expected, but that's not what seems to happen. I've tested this a couple of times now, and if I create point features at the elevation grid cell centers, save the GM session, exit GM, come back into GM, and open the previous session, the point features overlay does not reload. All of the other overlays I previously created open up, but not the elevation grid point point features.
Do I have to export the points before GM saves them? -
What version of GM are you using? There was a bug in some early v15 builds with saving the Lidar point cloud created from grid cell centers. If you get the latest from Global Mapper Downloads it should work. It just did for me when I tried anyway.
Thanks,
