Hi, I'm having a really weird issue with a file. When I copy something it takes a while, the color flywheel starts and the when I paste the element be it a wall, slab or object it pastes an exploded view. Now it sometimes doesn't even copy and I get the message that the clipboard is empty. It's a file related issue as with other files on the same computer I don't have this issue. With some objects the copy paste works and they don't get exploded.
