Hi @DeFlosser and thanks for reporting this!

To be honest, the exporter has some issues (this one in particulary) that need to be fixed but we didn't have the time to work on. It seems to come from the KSP file herarchy, like the exporter having trouble to find the files it is looking for, and loading a bad mu file, or a mu file that has a structure that is not expected (an update that has not been taken into account in the reader)

I really need to spend some time to fix this, so thanks again for the report and for making us coming back on this project.
