Making History structural panels sometimes get all @#$%ed up when using Ctrl+Z (undo)

[Ben J. Kerman]

Sometimes when I undo (Ctrl+Z) on a craft that has a lot of the Making History structural panels, the panels move all out of place and get messed up and I need to manually fix them or just give up and start from scratch. It does not happen often, and I think it has only actually happened to me three or four times. I am just wondering why it is happening, if it is a known bug, and if there is anything I can do to prevent it. Below is an example of one time it happened. I removed a few panels before I took the screenshot, so this isn't exactly what happened, but it shows how the panels moved.

*sigh* KSP is an awesome game, but full of bugs and glitches. Some are fun, some are not, and some are really not.
