I have a problem with the Riverwood area in the game at the moment, and I've been having CTDs when approaching the area. I verified the integrity of the game cache in Steam and this seemed to help possibly remove the CTDs, as then I could actually walk into Riverwood, but when I get there, there are walls and buildings missing, objects sitting in mid air, and some buildings quickly flicker between being visible/invisible and don't appear fully visible until you walk right up to them. Also, there are trees which appear like blurry 2D cardboard cut-outs.
Before I go through the painstaking 'uninstall all mods and then re-install them one by one' process I'm just wondering if anyone maybe knew of anything in particular that's been known to cause this, or if anyone has had similar problems and how they solved it. I only have 1 scenery mod in the Riverwood area, but this hasn't caused any problems previously and hasn't had any recent updates that could have changed anything, so I honestly don't think this mod has anything to do with it.
Any help would be appreciated.
