I am only at around 30hrs in and I have started to get freezing now too

It started with npcs dialogue freezing if I wanted to do another action as they tried to speak to me, but it eventually caught up and unfroze after a few minutes eventually.
Now it has started freezing solid and I need to re-boot the xbox to get anything to respond.
They also need to fix the weapon stands in houses too as I now can't use them?

I also get an annoying glitch where artifacts appear/tearing as you turn, a bit like seeing something out of the corner of your eye. At first I thought I was seeing things or it was butterflys close up, but it isn't.
I have cleared my xbox cache by manualy deleting old save files and trying the RB+LB+X as it boots, but no difference.
Brilliant game, but needs some bug fixing please!
