HDT Physics Extension NPCs Disappear: A Troubleshooting Guide

As a Skyrim enthusiast, I've encountered my fair share of frustrating bugs and glitches while exploring the world of Tamriel. However, one issue that has consistently left me stumped is the disappearance of Non-Player Characters (NPCs) due to the HDT Physics Extension mod. In this article, we'll delve into the possible causes and solutions for this problem.

The first step in troubleshooting this issue is to identify the mods involved. I've found that installing multiple mods can sometimes cause compatibility problems, leading to unexpected behavior. In my case, I was using a combination of SR:LE (Skyrim Revisited: Legendary Edition) and its associated custom content, including HDT Physics Extension.

To isolate the problem, I decided to start fresh with a clean install of SR:LE, following the main guide to the letter (with only a few minor modifications). Unfortunately, the issue persisted, and my character remained stuck in the infamous T-pose. But this time, it wasn't just me – other NPCs around me were also affected, refusing to move or interact with their surroundings.

To troubleshoot further, I tried loading different saves and re-entering the game, hoping that the problem would resolve itself once the characters had spawned properly. However, the issue remained, suggesting that the problem lay not with character creation but rather with the game's ability to render NPCs.

After extensive research and experimentation, I discovered a few potential solutions to this problem. First, make sure that all mods are up-to-date and compatible with each other. In my case, I had installed an older version of HDT Physics Extension, which may have caused conflicts with SR:LE.

Second, try disabling any mods related to character physics or animation. While these mods can enhance the game's visuals, they may also interfere with NPC movement and interaction.

Finally, consider reverting to a previous save or reinstalling SR:LE from scratch, ensuring that all files are correctly installed and configured.

In conclusion, the disappearance of NPCs due to HDT Physics Extension is a frustrating issue that can be caused by a combination of factors. By following these troubleshooting steps and ensuring mod compatibility, you should be able to resolve this problem and enjoy a more immersive Skyrim experience.
