I'm using TBC v5.2 with patch 2 installed.
My typical workflow for importing survey field data is to import the .spj file to a blank TBC project, do any editing, export it to a .vcl file and import that .vcl file into my main working TBC project file. With 5.2, when I import that vcl file it is blank. Even if I try importing that vcl file into a second blank TBC project it brings in nothing. There are points that show up in the project manager, and if I use the select all command it appears to select everything but nothing is visible and when I select the points in the project explorer they do not have any coordinates. I've attached an example .spj file that seems to import correctly, and the corresponding .vcl file I made from that that does not import correctly.
