So, recently, I have been getting many, many bugs with Fallout 3. First, the heads of NPCs start spinning around exorcist style, and secondly, NPCs sometimes move without a walking animation. For instance, let's say a follower is standing still; if I start moving, they will stay in the standing still animation, but still move in my direction when I move. Third, and the headbanger, is the most recent bug I encountered. After getting the G.E.C.K from Vault 87, I encounter the Enclave ambush; I never black out though, and just end up staring at them forever. I work around this by going into free camera mode with the console. I then proceed to disable one of the Enclave soldiers, then enable him; I repeat this until I do black out. Problem is, I get transported to the prison cell and, after lying to Autumn about not knowing the code, he and Eden never start their little talk with each other. This issue happened with The Pitt as well, where Ashur and that one guy who I happen to forget don't talk with each other after you first go to meet Ashur. I worked around that problem by resetting the quest and then setting the stage of the quest to 10. Obviously, I don't think that will work here since I'm trapped in some kind of cage. Disabling and Enabling Autumn or the little eye thing that Eden's voice comes from does nothing. The links are some screenshots of the bugs I spoke of first that aren't gamebreaking. I'll also give my mod load order, just in case anyone can point out what might be causing this.

Finally, I never encountered any bugs when using the vanilla Fallout 3, so I suspect it has to be one of the mods I'm using. I tried disabling some of them before running Fallout 3, but that didn't do a thing either. On images 2 and 3, pay attention to the feet and you'll notice that Bill's feet don't seem to change animation.

Also, I wasn't sure where to put this; since the issues cropped up after using the mods, I assume I would put it here.

I recommend:

1. Click on the Fo3Edit icon in my sig.

2. Download the manual and take a peek.

3. Use the links in the tutorial to download Fo3Edit and set it up.

4. De-conflict your universe.

Luck!

I have a headache after trying to wrap my head around all of that. Fortunately, I did manage to change the quest stage using the console, and then I disabled the force shield with the console too, then enabled player controls. Buggy animations still exist, and sometimes scripted talks between characters don't always work right, but thus far, I've managed to activate Project Purity.

EDIT: I deactivated all of my mods and tried starting a new game with Fallout 3 and the DLCs. Even there the NPCs weren't walking right, so I deinstalled Fallout 3 and then reinstalled it; now they are walking right. I don't know what in the world caused this, but thanks for trying to help me Miaximus.
