CSV import does not work with Epic Links

[Christian Mahlknecht]

Hey everyone

I created a "project" as a template with 5 epics and about 70 tasks and 50 sub-tasks, because we need 70% of these epics/tasks for each project.
Each task is linked to the respective epic.
The CSV export and import was done normally and works except for one small thing. The order of the tasks in an epic is not the right one after the import. How does Jira behave during import? First, all tasks are created in order by key ID and then the links are assigned? In the detailed log after the import I only see "all tasks created" and all sub-tasks have been assigned to the tasks but I don't see the assignment of the tasks in the epics.

Can someone describe to me exactly how the import works?
