Possible Bug: Error message when student appears twice in export
Summary
Apparently during the last c course exam there was a problem with the ILIAS export where a student appeared in two rows of the export file and and the accomodating table sheet was empty.
Steps to reproduce
Example Project
What is the current bug behavior?
The converter apparently didn't issue a warning when it was used at that time. I'm unsure if this may already be fixed in the latest version.
What is the expected correct behavior?
The converter should output helpful error messages/warnings in case any irregularities (like a student appearing twice) appear.
Relevant logs and/or screenshots
Possible fixes
Check if students appear twice, output a warning if they do.
