Since yesterday all the child issues on my board have been unlinked from their base issue. The result is that all subtasks are now visible at the bottom of my backlog, without a link to their original base.
I can't fix it myself manually, since changes on sub tasks are not saved. e.g.
- When I move a subtask to another column on the board, then refresh, the subtask in on the old position again.
- When I create a new child issue it appears on the board, but woth being linked to the base issue. Including error (see image).
How to solve this?
