Do what I'm doing.

We don;t know what glitches are in Dragonborn. Back up your save before you even install Dragonborn. Copy your file to a USB or use Xbox Live Cloud.

It'll save you guys some frustration if something catastrophic happens.

True story. As of Dawnguard I started saving every five minutes just for the dialogue options I was missing, and it certainly saved me once or twice.

Yes, I already found a glitch at the beginning that would have made me miss some of the content, had I not saved beforehand to be able to reload and see it.

Thanks Xbox guys for beta testing it for me!

...share the glitch then?

This is the no-spoiler section so I won't spoil what happens (and you have to see it to believe it), but try taking the very first boat ride while overencumbered.

I like to live dangerously... I don't back up, but I do load my most recent save and save to a new slot immediately. So far, no problems.
