Carlson2023

I am curious if anyone else is having trouble with Carlson2023 and 3d pline elevations. I've got a tech support issue filed with Carlson, so they are looking into it, but the technician seemed to be unable to replicate the issue the first time I contacted about it.

I have Carlson2023 installed on AutoCAD2023 on a Win10 computer. When I run Field to Finish on survey points, everything looks fine. As soon as I execute QSAVE or SAVEAS, all the 3d pline vertices at the survey points drop to zero elevation. The interpolated vertices keep their elevations. Its baffling to me how saving the drawing would cause the z-values to change. Has anyone else experienced this issue? Sticking with 2022 software version until Carlson figures this out.
