Loot Unreachable / Graphical Glitches

I am having various issues with Loot either so far below ground that while it shows on a ping there is no reaching it, even using the 'F' key, NPCs rubber banding all over the screen while I am in a conversation, NPCs initiating a conversation with me and then walking away like I declined to help and then have to click on them and talk to them again, spinning of rock faces or bits of the scenary flickering on and off. None of these, save for the unreachable harvestables, were present during launch. They only started up for me after patch #1.

There is some Ghouls Beard in the Hissing Wastes you can't reach, some mineral embedded in the stone walls outside of the first dragon's nest in Emprise Du Lion that highlights isn't interactive, a book in the Villa Maurel in the Emerald Graves on a bookshelf that keeps shifting position when you try to grab it (must use 'F'), and some plants near the Briathos Steps camp that are so far below ground you can't get them.
