I can paste smaller structures fine and undo them fine.  But when pasting the first larger structure I've ever tried to copy (a mid size single player base with external TCs, high external wall, etc) I get the following exception in the console, and cannot undo the paste.  Any ideas?

Did you use any third party versions to copy things? To what files and structures does this happen? And make sure there are no xmas lights. Send the files related please.
