Spent couple hours on my mod project today, doing some of the necessary but boring part of adding items to leveled lists. I got to a good stopping point, so I saved and closed the editor, and started up Skyrim to take a look at my handiwork. One of my swords was not appearing, and I realized I didn't set the first-person model of the sword, so I go start the creation kit to quickly fix it, or so I thought.

I load up my mod as always, with the error, "Navmesh 0003something blah blah blah" I hit "Yes to All" like I always do on startup. However, now whenever I load my mod it crashes right after I click yes. I know its unrelated to the error, but I'm fairly sure something is missing a reference and is causing my mod to crash.

I have a backup from a while ago... but its long enough away where I'd rather try to fix what I have. How can I change or delete the part of my mod I believe is causing the issue without having to open it in the creation kit? (since it crashes) Or, is there another culprit at work that I am missing?

I'd like to add Skyrim still plays the mod fine, (except the invisible sword), and that the creation kit loads any other mod up fine.

In case another has the same issue - I was able to solve it in a glitchy way by recreating the items in a second mod with the same name as the items I suspected were the cause in the first mod. They were done correctly this time, and by loading them both up in the creation kit at the same time they conflicted (because the items had the same name), and I just happened to have it load in the right order for the new items to work over the old ones. I had to do this without an active file so saving would give me a new combined version. I still have some to redo, but not the couple hours of tedious crap I don't want to do again. Thanks anyway mod community
