I am having trouble copying and pasting features. When I move the copied feature to it's new location, the old feature disappears. It's still in the attribute table, but it seems to move to the new location along with the new, pasted feature. Even though only one feature is highlighted in the attribute table, they both seem to move.
Also, is there any way to flip a feature? I have lots of identical rooms to digitize, all the same size, but with doors on either left or right, so I'd like to flip a feature with the door on the left to one with the door on the right.
