Thanks for the report. This is a known issue that was logged as JIRA UE-16909. I’ve added more info and let the devs know that his is also being reported by you. Follow that link to monitor the status of the bug.
I furthermore happended to notice that movements done via piloting are currently not editor transactions. Meaning that they cannot be undone with Ctrl+Z etc.
That should also be a separate bug report I guess.
