I seem to have an issue with bulk importing project tasks.
i made an export to get the format of the needed csv and built the right new one, but while it imports everything else fine, it ignores the parent-ID on sub-tasks, instead creates a new task. (type sub-task is defined, Parent Task ID is defined, yet it ignores that).
how can i bulk import correctly, i.e. having sub-tasks also created with the correct parent task?
