it did roll back a few renders but seems to be a common thing among some avn's
you can try it ,it worked for me ,if it doesn't then you could try other methods suggested
if you can wait, i suggest waiting for the proper release which should be in a week or 2 (IMO the update was more off a fan service lewd update then any real story progression but a few non - lewd things did happen)
