AI Overhaul for USLEP (USLeEP)
v1.3
by Darklocq (based on prior work by SpiderAkiraC and by Arthmoor et al.)
2021-06-05

This is a patch (actually replacement) of AI Overhaul, which dates to 2014-15,
to be compatible with Unofficial Skyrim Legendary Edition Patch and the DLCs.
AIO improves the behavior packages of numerous vanilla NPCs, but it undid many
USkP and later USLEP bug fixes of them (and even some basic changes by
Dawnguard to a vampire NPC, and by Hearthfires to a child NPC, not to mention
Dawnguard's adjustments to the entire game world's Max Height Data record, and
Dragonborn's similar tweaks to the Windhelm worldspace).

Now you get ALL the fixes.

AIO mostly changes NPC AI packages (when they wander and where, when they
sleep, and so on). USLEP fixes many glitches in NPC records like who
will rent a room, who has what key, dead body cleanup, missing object bounding
boxes, strange coloration, mages with no spells, missing faction membership,
and so on, and other fixes (like part of Winterhold not getting Winterhold
weather). Arguably the USLEP changes were more important, but the STEP Project
was actually recommending AIO anyway, so the conflicts really needed to get
resolved, since everyone heavily modding Skyrim is following the STEP guide:

Requirements and Installation
=============================

This requires Unofficial Skyrim Legendary Edition Patch (USLEP or USLeEP):
https://www.nexusmods.com/skyrim/mods/71214

That, in turn, requires all of the DLCs and Update.esm.

The original AI Overhaul is not required (it's just an ESP and this patch
replaces it). Consider downloading and endorsing it anyway, just for modder
goodwill. :-)

Install USLEP first. If the original AIO is present in your mod manager,
uninstall it next. Then install my fixed AIO (other mods can come between
USLEP and this; they just need to be in that order in relation to each other).

Install this like any other mod, whether with a mod manager or manually.
In a manual install, if asked to overwrite an existing "AI Overhaul.esp" then
do so.

If you also use "Ethereal Elven Overhaul", then you'll need "Ethereal Elven
Overhaul and AI Overhaul Patch for USLEP and STEP", which installs after this.


Notes
=====

1. This mod is not a magic cure-all. If you install various NPC replacer
mods, many of them will also need patches to be fully compatible with
AIO, since it changes some "popular" NPCs like Farkas and Aela. (Most of
those mods are already USLEP compatible.)

2. AIO changed the global game setting fAIInDialogueModeWithPlayerDistance
to about half of its vanilla value. This verseion doesn't change that, as
the change is probably desirable to most players. You need to be a
conversational distance from NPCs for them to have conversations with you.
If you don't like this change by AIO, you can undo it yourself in TES5Edit
or the CK (it's GMST record 0002a37e).

3. This mod has nothing to do with "Immersive Citizens - AI Overhaul" or
"Enemy AI Overhaul - Revenge of the Enemies", which are unrelated mods.


Permissions and Credits
=======================

I impose no restrictions of any kind on this very simple patching job.
AIO had none either. USLEP has none that affect patches.

AIO is by SpiderAkiraC, and this version just tweaks it. USLEP is by
Arthmoor and the USLEP project team.
