It's been always like that for a lot of people (myself included), hence they added a 30 second reminder before it happens so they won't get a sudden freeze when it combat or moving.

I've read that it isn't much of an issue if you haven't travelled a lot of areas hence the game doesn't really save a lot, but I'm unsure of that claim. Personal experience, sometimes it freezes me or sometimes it's just a straight up fps drop (not a complete freeze).
