Thank you for your report
I am unfortunatly unable to reproduce this issue, but given that functionality is fairly specific depending on exact circumstances, I'd be most interested in a save game of a situation where this happened (and any details on how you were editing / where you clicked etc.)
did the exceptions.log (found in the logs folder parallel to the save games folder in your documents) contain any entry that might be of value
