For some reason the Migration is called twice!

I am facing the following problem: The migration is called twice!

Here is my code: http://pastebin.com/wAPHrW8j

Please help.

If a doc is changed drastically, it can move around on disk and then be
returned by a cursor a second time.

You can either write an idempotent migration or open your own cursor and
use snapshotting:

(pay heed to the warnings listed)
