Mine's still all in one piece, but I never really do anything with her. She just stands in a simple pose on the shelf. Not a Pre-Filmation fan so I initially only got her to have a complete collection. I later decided to work her in, but in my canon she's a villain and she's the one who created the Snake Men (not sure what I'm going to do with Unnamed One -we'll see once we actually see him)
At one point while moving her to dust the shelves her leg popped out of her boot, but it went right back in. It wasn't broken the peg simply came out of the hole.
