Wowza, I have no idea. That looks like layer shifting to me, which is usually indicative of a mechanical error on the printer, like a slipping cable or something similar. But if it's only happening on this print and nothing else then I really am not sure; maybe others have had this happen to them? I always use Slic3r PE since I have a Prusa and have never had a problem like this. Sorry to not be more helpful!
