Help!!! While using a pretty large form with root line and many dynamic dropdowns, I tried to move a specific dynamic field to the top of the form. After moving it, I updated the form and a red message popped out  "You do not have permission to do that" I double checked I was signed in, which I was, and tried to update again. This time the form updated successfully but it deleted the field I had moved and every page except the 1st one. 8 pages were deleted in an instant, without anyone clicking delete on anything. Is there any way to roll back to a previous version of the form?
