Right, I've been testing and testing my PC Skyrim after recovering from my dead hard drive a few months ago. Looks like I've fixed practically everything, including serious CTDs and lock-ups with Whiterun, Solitude and Riften by uninstalling all the obsolete Towns and Villages and Beautiful Whiterun mods. The only things that look like they need sorting out now are two places, the area approaching Lakeview Manor and entry into Jorrvaskr.
Firstly Lakeview. I've been having trouble travelling any distance away from the manor in any direction. About the furthest I've managed to get is to the road to the north west, to the necromancer to the north east, and to Pinewatch to the south before everything stutters and locks up. Turning off Skyrim Flora Overhaul didn't seem to work, so I've looked on the Wiki bugs list and:
"The system may instantly crash upon attempting to approach the area around the manor"
Yep, that's pretty much what I'm getting, except for me it's when I travel away from the manor rather than towards it. But my guess is approaching the manor would have the same effect.
Then there's Jorrvaskr. I've read about others not being able to leave the building due to infinite loading screens. However, my trouble is the reverse. I'm not able to enter due to infinite loading screens. Again, the wiki describes the exiting bug but not my entering bug. My guess is that it's probably caused by the same thing?
Any idea how to fix these? I've got the latest SKSE, but I understand there's a separate mod to stop the infinite loading screens?
