I cannot seem to reproduce the bug exactly. I am sorry.
But is does happen a lot and is very frustrating.
I work almost everyday on editing, recording and re-recording midi to real instruments and I encounter this problem many (unexpected) times.
I do notice that files tend to get corrupted near edits and near the end of a file (last 10 or 20 bars)
