Files changing order in timeline view
When using the timeline view, if you move multiple images at once, the order of the files is reversed instead of preserved when you drop them in the new location. This is causing a massive headache for our work group as our whole days are spent rearranging files to specific orders.
The mentioned issue is fixed in the latest patch release #18.104.22.1683, Please install and confirm if that fixes the issue.
