Yeah that's what I meant my apologies. I did try to copy the file again, and it still led to a CTD. I attempted a fresh install as well as a brand new save game which still crashed. Edit: Just wanted to give you a little update, after playing around for a while, it seems the dwemer lod mesh resources folder from Oldrim work fine as a replacement and also prevent the crash after being optimized for SSE.
Hi, just wanted to tell you I have a similar problem (almost exactly the same) as jtharpla. The NetScript crash logs pointing to the same .nif file, and the crash being solved by doing the same file replacement. I attempted to do a fresh install first, and that still led to a crash. However, like jtharpla, I use a mod that modifies markarth (The People of Skyrim 2). I used Dyndolod ver 2.8, Skyrim 1.5.80, and Resource ver 2.7.
