It's caused by using the Mods menu in the Fallout 4 menu.

 

AAF requires LooksMenu to work.  Unfortunately, LooksMenu's plugin will always get deactivated if you use the Mods menu, due to the way the plugin is constructed.  So if you go into that menu, LooksMenu gets deactivated, which breaks AAF.  You can just use a different mod manager to reactivate LooksMenu and that fixes the problem.

Basically you're saying to use MO2.  I did go into the Mods menu within FO4 and that's when this issue started.  Unfortunately, reinstalling Looksmenu via Nexus and Vortex didn't solve it.  I guess us Vortex users are screwed.  I've used MO2, and it's great, but so much control for someone who's not as advanced as you are.

For anyone reading this in the future for help:

 

As stated above using The Mod menu in the launcher can cause this.

Several posts across the internet claim using Fallrim tools Resaver on the save file can help - (not)

 

One other thing that will cause this to happen is corrupt or mismatched files for F4SE.

So re-installing F4SE from a fresh download will fix the majority of these errors, and allow you to load your saves.

 

On the AAF Discord is a download of a tool - AAF-GFV.exe, installed in Game install folder, and added as an executable in MO2,

is how to verify a lot of your installation. Sorry Vortex users, no idea how that would work for you.

Can't get ReSaver to even start. Fresh install of F4SE did nothing. And running AAF_GFV just gave me this (see attachment). What the Hell am I supposed to do with the latter, especially when a third of the fields say "Work in progress," does absolutely nothing while on, and the only thing I can click on is the Exit button?

GFV is for 1.10.163 game version. 

 

What's the problem by the way?

Oof.

 

Every time I try to load a save, I get this error, along with one saying that either the Amputation Framework didn't load or something went wrong with UAP, and using console codes to restart AAF only causes the message to repeat.

And what happens if you start a new game? 

 

I haven't seen that kind of error and I'll guess that save is fcked up. If you can start a new game and everything loads up correctly, then save is corrupted unfortunately...That means only the new game will help or you can try to search/load the save which is not messed up. I haven't seen that kind of problem with AAF, but I know that sometimes uninstalling workshop mods and loading same save, this save is corrupted and you need to load earlier save where mod wasn't loaded...

That's the thing, though. New games consistently start just fine. The problem arises whenever I try to load a save. Every. Single. Time. And whatever's happening is affecting every other mod down the line, because trying to continue causes triggered scenes to lock up with nothing happening. I already followed the AAF installation guide to the letter.

 

Annoyingly, I'm not even sure if the problem is limited to just this issue. I can't even recall triggering a sex scene prior to loading a save, but that might just be down to subjecting my character to DD/KT gear without corresponding animations (I can't tell if any of the animation packs available have support for those).

 

At this point, I'm seriously contemplating giving up on FO4 and simply going back to Skyrim.

Well, Skyrim modding is more complicated, tho. But that's my subjective thoughts...

First error about SUP F4SE - you are missing this mod or have installed wrong version for your game

 

 

And Ego explained here pretty well about this error. I'm afraid you need to start new game, because of that [074] error. You said that new game is ok, so...

Can you post your modlist? Not plugins, but mod list...

Based on what you describe, it sounds like you have a mod in your build that repeatedly corrupts your saves. AAF is simply letting you know.

 

You have to do the work of disabling/enabling mods (likely culprits first) and testing until you figure out what is incompatible, broken, misconfigured.

Yeah, I briefly got AAF to start up last night (never did that before) while monkeying around with my load order. Failed when I tried loading a save though. This is going to take a while...

It's been a while since I dabbled in playing a Bethesda game, long enough to forget most of the ins-and-outs of the process and have to relearn all over again. I also have next to no prior experience adding LL mods to FO4, most of that I previously did in Skyrim.

 

And yeah, pretty sure at this point it's a question of load order/priority. Any advice on where to put AAF and UAP relative to everything else (e.g. Amputator Framework)?

 

Edit: And now I have an entirely new problem. Now, every time I try to start things up, I get the message "cbp.dll disabled" and a strongly worded warning NOT to start. Attaching load order.

Pretty big mess in your mod order. You are not using separators and not arranging mods on your left. For example OCBPC-0.3-ZeX4 is disabled and under MTM preset. Should be OCBPC-0.3-ZeX4 and MTM overwrite OCBPC. And lot of disabled mods as well, so it's hard to understand anything. And AAF/LL mods is messed up as well - you need to organize them at the very bottom in the left pane. 

 

May I suggest reorganize your left pane - use separators for each category (it will be easier for you to find mods, if anything goes wrong) and there are some tips/tricks for left pane as well. I'm not sure if your problem is caused by wrong load order, but left pane is important. You can search for order in google, there are several good tips/tricks for it. And for AAF/LL mods there is a manual in the forum. Looks like that you didn't read it. 

 

About your problem - I would start with reorganizing of left pane (order, separators), delete mods which you will not use for now. Use alternative start mod for skipping Sanctuary/Vault area. Test important AAF things in early game (animations). Physics you will see in very beginning. Double check if mods are compatible with your game version - I'm using downgraded game version and keeping all AE stuff. There could be some problems with AE game version and some mods (compatibility). As I said - you need to double check.

Okay, first off, thanks a lot. Never noticed that functionality before, and it took a while to figure out the ins and outs of it, but that smoothed things over immensely. AAF and most associated mods are working now.

 

I have a new problem, though. The female model and jiggle physics aren't working properly. Unfortunately, I also have a lot of mods that are designed to play with body morphs and sliders (Rad Morphing Redux, Wasteland Eggspansion, Mad Science for Dummies, etc.). Currently, the breasts hang at chest height, regardless of movement (looks especially weird when someone is crawling), and the sliders don't noticeably change. Which skeleton/meshes/physics should I use to produce the effects I want?

As I understand, you are using CBBE body. Which main physics mod you are using? You need main physics and MTM preset. Might be that you are using wrong main physics mod. And there is/was one thing with physics - it tied to in-game FPS. So, if your pc can't provide pretty stable 60fps, there can be problems with physics. 

 

I found this OpenCBP version for AE. And looks like that with this one there is no problems with fps as well...

 

I'm using Fusion girl body and I never used CBBE, so, it's possible, that  my suggestions about physics is quite wrong

In tandem with HiPoly Faces Redux, that seems to have done the trick. Thanks again
