Wireframe geometry. All z=0, lines, arcs, polyline with some groups and blocks.

We have been saving all files as AutoCAD 2013.

Good day to all! I haven't been able to find anything searching through the forum, if someone can, please reply with a link. We have MasterCAM 2017 and just upgraded to AutoCAD 2019. Within AutoCAD, we save all files as 2013 for our saveas and w blocks. We have a template MasterCAM file that we erase all geometry and file merge, then re-chain and save as. Since we've upgraded to AutoCAD 2019, the file merge function in MasterCAM randomly crashes MasterCAM with no error warning. Just disappears. This has been happening seemingly randomly over the last week and we have not been able to find a consistent factor in the crashes. With the files that do crash, we just re-do the process in AutoCAD and it seems to fix it. Any help would be much appreciated.
