Be sure to use LOOT to sort your load order. I'd recommend switching over to Mod Organizer too.
Much easier to see conflicts that way.

Don't think it's a conflict tho...same with the bug which makes your sometimes hold your rifle in the wrong hand it's sadly unfix able

Did uninstalling and reinstalling help, @Aznmagicalman?

It worked! Tested out in the Kings, no invisibility.

Ah! That's good to hear, man!

I'm Blessed! Now if anyone asks then simple tell them to uninstall and reinstall the game.

EDIT: I take it back, while it did take care of other locations. Camp Mccarran is still having problems.

Ya to say again while it worked for part of it, still blanking out in McCarran. And while I don't blank out in the Kings, Cass' head vanishes.

What mod are you using that affects Camp McCarran?

I definitely ain't weapon, armor/clothing, companion or animation mods that's for sure.

I think it may have to do with the NVSE

Yeah, I had to turn off all steam overlay because of the ENB bug. Everytime a friend came online or played a different game everything became invisible.

Well for me it's different since unlike Steam Overlay, it mostly has to do with going to certain indoor locations which makes my body invisible whenever I'm in Third-Person or looking at my body (I use Enhanced Camera) or other NPCs like my Companions who would either completely turn invisible or parts of bodies would. The locations I can list causing invisibility are:
- Camp McCarran by Curtis' and the Interrogation Room
- Vault 22 Hallways
- Kings School of Independence Hallways that go upstairs
- Hidden Valley Brotherhood of Steel Bunker in the Hallways by Eldar McNamara's Office
- Gomorrah Casino Suites

I remember someone saying one of the Videos of Gophers Playthrough had the same problem. Which New Vegas Playthrough was it since I'm currently searching for tons of Gopher New Vegas playthroughs. I can read the comments section if there's any luck.

EDIT: Restarted to a New Game to see what happens.
