Corny heading I know

I picked up the M200 I gave to my wife & started writing only to find that it was the scratchiest pen I have had in my hands .. I know when I gave it to her it was one of the smoothest .. so I looked under a strong mag glass & saw the right tine had lifted (or conversely the left had dropped)

I don't the reason or cause of this ... what could have happened to it for the tines to pop?

And what to do to correct?

incidentally apart from the scratchiness the lettering now has more character

I had the same thing happen to the nib of a 215. My wife had been using it for several months and when I went to write with it it was just as you described. After looking at the tynes with my 10X loupe I thought it may have been dropped or something, but my wife said it hadn't been so I returned the nib to Chartpak, who replaced it gratis. The replacement nib coniues to function flawlessly.

Aside from being dropped, the tines could have become mis-aligned by not being careful when the cap was put on. You need to take are that you don't just drop the pen into the cap or jam it on without thinking that the inner cap is there and the tines could be hitting it when the cap is replaced.
