So, this is gonna be really weird, but I've had a horrendous problem as of late in which NPCs glitch. Every time I enter any area (currently Nellis AFB & the Boomers), NPCs flicker on and off, and I can see them flipping between different sets of weaponry as they phase into and out of existence. It settles down after a bit, but it happens every time I enter a populated area, aka everywhere
By the way, this also cause intermittent pauses as the NPCs fade all around. As mentioned above, I thought it was a bug with the spawn rates and how IWS handled spawns, but I was mistaken.
I have a feeling I'm missing something insignificant, but I wouldn't even know where to start. The only other mods I have that even touch NPC spawns, I think, are Monster Mod 10, Warzones, and maybe Repopulated Wasteland. However I turned off Repopulated Wasteland with no change.
Here's my mod list, but I've looked through it again and again, merged patches with FNVEdit, and made sure the load order is correct with BOSS. I'm stumped, and I really want to keep playing with the increased spawns. Also, I've noticed this even happened on Veronica too...
