Thanks for the reply. So basically, because of the way mods and patches are written and the abilities/knowledge/skill of the author, it's a complete crap shoot whether any particular update will bork your game. You've pointed out an issue I've had crop up several times where an update to a MOD invalidates all the patches written for it so the MOD would play nice with other MODs. I use Vortex (I'm old and MO2 is beyond me) and you can't leave MODs/patches with no master in the load order - so another new game. I actually want to play the game and see what the MODS actually do but it seems like after getting hours into a playthrough, some new MOD or patch will come along and totally corrupt your game. Just me ranting I guess. I'm on new game, I don't know, 10? for December and now trying to find out what is causing a CTD when I get close to Dawnstar. Will I be able to find out which MOD/patch is causing it? Probably not. It could be something installed or something missing. No way to find out for me.
