I just finished installing 1.8 update on xbox 360. I travelled by carriage to the college of winterhold and the whole college is glitched with textures not loading, flickering textures, wierd brick walls appearing out of no where which can be walked through, ground missing. I am going to search other places for this issue.
Its the first time it happened to me ever. And it was straight after the patch. Hmmm fix this. It seems to have fixed my water texture/mesh loading issues. But I may have to check every now and again.
I have been having that occasional problem since Dawnguard, not sure it is something they can easily fix. I was hoping 1.8 would improve how the game runs, will not get my hopes up now.
