It's definitely a bug then, and since I didn't run into it it's probably caused by a chain of events.
I'm suspecting the undo info is somehow corrupted and reintroduced, so some elimination:
Does it only happen with mpd's or also when using separate ldr files?
Does it happen when you restart after the split and before adding stepping?
Could you post a before and after mpd, maybe I can spot a pattern.
