So, I was playing Skyrim Special Edition, and as I was entering Whiterun Hold, a massive stretch of grey just popped up on my screen. I used TFC and found the source of it, which turned out to be a female bandit. Using the console, I killed, and subsequently resurrected the NPC, which fixed it. The problem is, this has happened multiple times, and it is either a female bandit or female mage each time. What could this be caused by? I do have mods installed, including those that affect textures and meshes, however, the problem persisted even with these uninstalled.
Any help would be greatly appreciated, as this is the only game with this issue.
