copy_cost_item appends the copy to the inverse relationships of the original cost item, which for a root cost item includes the source schedule's IfcRelAssignsToControl. copy_cost_schedule then assigned that same cost item to the new schedule as well, so the copies showed up in both schedules and deleting them from one removed them from the other. Unassign the copy from the source schedule before assigning it to the new one. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
