You're not wrong there, I leave this tab open in the event I have something to contribute; which I really don't . The only things I've found are thus:
1) Quest items are not a factor. I spent time going through each that I had, finding the ID, and removing it from my inventory. I thought maybe there was some type of interaction in some way. There wasn't xD.
2) I also spent some time in no clipping mode to see if there's a vertical high or low where there may be a way to pass over or under the area 'trigger' that makes the game crash; and it seems the answer is no. Whatever 'trigger' it is, I spent about a minute going in both directions and flying over/under and it did not work. Makes sense I guess.
3) And if it wasn't already obvious, it definitely has to do with the player character itself and not the camera, since if I toggle freefly camera, I can freely go past the points that crash me.
Also note basic obvious console command resets (aside form revertworld, as people have noted) do nothing. ie. resetAi, sixchanges, perk levels, SPECIAL levels, etc.
The funny thing is...it's probably some arbitrary choice we all made, like, nose size that causes something to just break. In which case, debugging this will be next-to-impossible. This, of course, coming from my complete lack of all knowledge in programming .
Thanks for your hard work Joe, and everyone else contributing.
At this point, I don't even care if the end-result is all current saves are compromised. I just want to know what the bug is, that it's fixed, and no one else will have to suffer such agony. Men in Black taught me bugs are bad...plagues of the Universe.
