<pre>Same happened to me a few times lately...
I wasn't able to reproduce it in any way but I had the feeling it
happens whenever you split a region, move the second one to another
track without applying any changes to it and later putting it back to
its original position.

BTW, I remember now: in my case the regions was two different audio
files, not splitted...<br>
