Go to the editor and place 300 blocks, then go back to the menu, then go back into the editor and the clones will look like they are deleted but you can't place any more blocks because the system still thinks there are 300 clones. Help.

That's because the clones are still left over if you return to the main menu. They are hidden, but not deleted. To delete them, you'll just need to add these two blocks to the Tiles sprite:

when I receive [Menu v]
delete this clone
