I found one source of the problem, being Real Wildlife...with that active, it was 100% of the time. Now its about one out of three times it crashes, if a single mod is active. I removed ALL Real Wildlife files.
However, it doesn't matter what mod is active...I can randomly select a single mod (everything else inactive) and the game crashes at that same spot. And it seems random in that area. It doesn't matter if it is just a clothing mod, or a companion mod or a graphics mod...it crashes in that exact spot. I deactivate that mod, and repeated attempts, and no crashing. Even if a clothing mod is active (one), it still crashes at that spot, and deactive, it stops...so I don't understand.
I tried a complete reinstall (twice) and same problem. On a 100% clean save.
Here is my mod list. I added notes to the more major mods and what would make "sense" to cause crashing.

I also use a Bashed Patch, but it isn't currently active. Since I'm trying to figure out what is causing this weird problem, where if only one and any mod is active, it crashes at that spot. If it matters, the more mods active, the more likely it crashes at that spot. However, again, Real Wildlife was the cause of it being 100% of the time.
Started happening recently, just 2 days ago. I barely changed what mods I have, almost all of them are what I've been using for ages. And I deactivate all the new ones, and it still crashes. Even after 2 reinstalls. And it crashes at that exact spot, even if I don't include "new additions" to my installs.
