The Beginning: Lvl 19 character. 1st and only character. Played without issue with Legendary Edition up to this point. Loading lots of mods.

PROBLEM: I have 56 saves at this point. Finished Gallows Rock. CTD when exiting dungeon to overworld. Game CTD on load screen when trying to load last (or any) manual save. Will load AUTO saves but will CTD when trying to exit dungeon to Overworld. Also CTD when loading manual save after loading AUTO save. Started brand new character. Tried to load manual save from there and CTD. Loaded AUTO save from new character and CTD upon trying to exit dungeon.

PC: Brand new beast NVidia 780 (3GB VRAM). Windows 8.1. 16 GB of RAM. Intel i5. Been running Ultra everything with updated drivers without issue up to this point.

MODS: Loaded all Mods from Skyrim STEP Project process (v2.2.8). I can't attach files here, but am listing my BOSS report and *.ini files below. I can post load order if that will help.

I updated my system primarily to play tweaked out Skyrim so losing this would really svck. Has anyone else experienced this? Appreciate any help.

EDIT - The BOSS Recognized Plugin Record is too big to post apparently. But there are 142 Recognized Plugins, all cleaned without error using TES5. No conflicts reported. If there is a way to post load order and it is helpful, I am happy to do that as well.
