For Crossover Charts in Expedition, I have just swapped from *.csv Crossover files to KND (*.xml) source.
I have just discovered when exporting an optimised route as a *.csv file, where sail overlaps occur on the *.xml crossover chart (e.g. J1/J2 or A2, A4 in specific TWS/TWA cells), the resultant optimised course *.csv file has sails in 2 columns rather than 1, and displaces everything else on that row to the right 1 cell. So far I have fixed by manual edits.
And tell me if I haven't explained this well!
Cheers
