Omitting --dayonly when appending to dayonly timelapse crashes the script

[xiagu]

I saw the comment "Options with a * do not have an effect when appending to existing timelapses." and got rid of the --dayonly option when appending my latest save. Factorio ran twice instead of once and the script gave me this error:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\iris\\AppData\\Roaming\\Factorio\\script-output\\FactorioMaps\\vanilla2023\\Images\\7\\nauvis\\night\\crop.txt'

This is probably expected (or at least working as implemented) for the script, so this bug is more about the documentation being misleading.
