I created an Event in the Scheduler, and dragged a few hundred items to the event.
Later, I added a few more items, but wanted them to appear at the top of the schedule, starting first.
When I dragged the items from the end of the list to the start, this happened:
That is, the item moved to the "top of the Event list" but its start time didn't change!
To get the schedule to render correctly, with the first item in the list starting at the intended start time, I had to
- disable the event
- change the interval
- put the interval back where it had been
- enable the event
