In the image above, I had to wrap the code between lines 48-53 to avoid an unhandled exception being thrown by _ColumnDefinitionMap.Add(offset, def). Note the warning message:
Warning: Duplicate offset 0 in sheet 'TiltParam'. Skipping.
Without the wrapper, Godbert would silently die when I launch it.
I also see in the output there are a number of error messages like the following:
Defined sheet ClassJobActionSort is missing.
Not sure if that is a problem or not.
