i am trying to do an obby and i did some stages. how can i order them from explorer to be from the best to the worst?
You can't. They follow alphabetical order.
You can always use characters like numbers and !, @, # to sort them alphabetically
In case the objects are just randomly sorted, you can change the order by deleting the Parent of the objects that you want to order and then undo that action; it should reorder them in alphabetical order.
