I am trying to import an external tsdf and esdf from a realsense lidar into voxl-mapper. I am looking at the code and only see the mesh is not used in loading a saved map, but just tsdf and esdf. The error I get is the following, which causes voxl-mapper to freeze.
```
Client requested load map.
full file name: /data/voxl-mapper/officetest/esdf
full file name: /data/voxl-mapper/officetest/tsdf
Version number mismatch! This needs to be handled...
Updating mesh
```
I grepped for the error statement but came up with no results, so I am not sure where in the stack the error is coming from. Any help is appreciated (edited)
