Internal Server Error 500 When Deleting Closed Engagements Due to Foreign Key Constraint Violation

Hi all, previously I cleaned closed engagements. If there was a finding that was an original of duplicates in this engagement and the duplicates were still present in other engagements, the oldest of these duplicates was set as original of the finding and I was able to delete the closed engagement. Now I always get an internal server error 500, when I try to delete these closed engagements: update or delete on table "dojo_finding" violates foreign key constraint I know there were some changes on the delete logic in recent releases but I could not find an info that what I'm trying to achieve is no longer possible. Did I miss any settings that I need to adjust?
