Load Order
Currently sorting your load order manually is the recommended way for organizing your mod load order. Atlas's guide, Proper Load Order & You. is the most up-to-date and accurate method for organizing your mod list. Once you have your mod list sorted, backup your mods.cfg file (located in the data folder of your Kenshi game installation), as that is what keeps your load order organized.

The Unofficial Patches for Kenshi (UPK) is intended to correct issues in vanilla gameplay, and therefore follows the Overwrite Rule as outlined in Atlas's guide. You will want to load this mod near the top of your load order, likely the last to be loaded under [UI, Graphics, Performance], and let it be overwritten by other mods:

[UI, Graphics, Performance]
All other UI, Graphics, Performance Mods
Unofficial Patches for Kenshi
[Animations]
etc.

Patches
All Patches provided by the UPK only affect UPK values. For example, the Unofficial Patches for Kenshi - Reduced Stones and some Other Foliage Patch doesn't change any values with Reduced Stones and some Other Foliage, it only changes values with the UPK. Therefore, rather than load the patches at the end of your load order as outlined by Atlas, you may instead load them immediately after the UPK:

[UI, Graphics, Performance]
Unofficial Patches for Kenshi
Unofficial Patches for Kenshi - Reduced Stones and some Other Foliage Patch
[Animations]
...
[Overhauls & Big additions/world changes]
Reduced Stones and some Other Foliage
[Patches]
etc.

Mods that Add and Edit Races
Since the UPK utilizes Cattrina's Vanilla Toe Fix, custom race mods will be incompatible, though playable, if they use the original female foot mesh. A compatibility patch between said custom race mod and Vanilla Toe Fix will be required in order to resolve this issue, or just ignore the mesh bug in favor of playing with your custom race mod.

Some animation, character and race mods will overwrite the Vanilla Toe Fix mesh included in the UPK. If this happens to you, you will need to download Vanilla Toe Fix separately and load it after those mods.

Mods that Change Faction Relations
The UPK makes multiple changes to faction relations. If you decide to install the UPK mid-gameplay, these relationship changes will not take effect. You will need to import your existing save in order for your faction relations to be updated.

In the event that importing your save is not an option, usually due to experiencing additional bugs with faction conflicts, I recommend following the solution outlined here: https://www.reddit.com/r/Kenshi/comments/bwmw51/a_rant_on_factions/

If you experience the rare bug in Kenshi after importing a save that causes certain shops, buildings, NPCs, and even enemies to not respawn correctly, Ruhadre has created a mod called Guaranteed Shops that may be able to help fix the issue. Please read their instructions carefully before attempting this method.

Mods that Add Buildings
New buildings are one of the most common mod types that can lead to compatibility issues. This is partially because all edits made are inside the game, not the FCS. Your best option is to test mods together, go to locations heavily modded by the authors to see if they are compatible or not, and decide which ones to use. Unfortunately, there really is no easy solution to this problem unless a compatibility patch can be found or created (i.e. Unofficial Patches for Kenshi - No Stone Camp Trader's Patch).

Mods That Edit Meshes/Textures
Depending on how the mesh/texture fix is implemented by the UPK, some changes may be more incompatible than others. The reason is largely due to whether or not meshes/textures have to be remapped. By default, as long as the file pathing in the mod mirrors the base game, Kenshi will instead read the mod's files. Certain files, however, need to have the FCS point directly to them in order for them to work. Having a proper load order as outlined above should resolve the majority of these issues.

Mods that Overhaul Kenshi
Overhaul mods fundamentally change multiple aspects of Kenshi's gameplay. While the UPK intends to be as compatible as possible with other's content, there inevitably will be issues with some of these mods. Here are the currently known compatible/incompatible mods with the UPK:

TBD

• Odyssey
• Equinox Overhaul
  

Compatible

• General Modifications (GenMod) - Requires the Unofficial Patches for Kenshi - No Stone Camp Trader's Patch.
• Kenshi Kaizo
• Living World (LW)
• Reactive World (RW) - Requires the RW Distant Towns patch if you want distant towns for RW.
  

Not Compatible

• Kenshi - Genesis - Currently there are no plans for a patch as my computer cannot handle running Genesis.
• Universal Wasteland Expansion (UWE) - A patch is planned, not a top priority.
  

F.A.Q.
How safe is it to install/uninstall this mod mid-gameplay?
Mods, when installed/uninstalled mid-game always modify data, and therefore run a risk of damaging and potentially corrupting saved gameplay. Kenshi's capability to import saves after mods are added and/or removed will fix several of these issues, but there is no guarantee it will fix everything. Because of this, I highly recommend always testing mods using a brand new game start, or at the very least back up your save game file before installing/uninstalling any mod.

Is this mod compatible with X mod?
Unless I have checked previously, I have no way of knowing if something is compatible or not. Feel free to let me know, in detail, if you've found an incompatibility somewhere with another mod, I will do my best to replicate it on my end to confirm if I need to adjust anything. Please also check the Files section of this mod's page first before asking, I may already have a patch available.

Is this mod compatible with Kenshi's experimental version?
Experimental on Steam is the latest, and most unstable version of Kenshi available. While there should be no major changes that would conflict, I cannot 100% guarantee that the UPK will work as intended. I have no plans to support the unstable experimental branch unless the developers finalize it in a future stable build.

Is this mod compatible with earlier versions of Kenshi?
The UPK is designed to work with version 1.0.59 of Kenshi. While it may be possible that the UPK will work correctly on earlier builds, I cannot guarantee they will, and I have no plans to support earlier editions.

This mod is causing crashes in this area/zone/city/town!
The number of reports I have received about the UPK causing in-game crashing have been minimal when compared to the number of people who download and use this mod. Every build I document all changes made in the Changelog specifically to help identify issues in case something comes up, and every release is cleaned by the FCS. Unless there is something specific to a change I have made, or there is a re-creatable error I can test for on my end, I can only ask that you troubleshoot more.

But Kenshi is still crashing, what do I do?!
Generally, whenever modding any video game, it is always recommended to follow all standard troubleshooting steps for that game. Verifying the integrity of your game files and importing your save are some things you can do for Kenshi. Aside from this, you can try recreating the bug to see if it's consistently happening, checking recently installed/large mods by disabling them and running the game for a while to see if it crashes, etc. The longer your modlist, the more likely you are to run into issues.

Why is the distant towns feature in your mod not working?
By default, distant towns is disabled by Kenshi to avoid performance issues. To enable this feature go to Options, Graphics, look for the option Generate Distant Towns and tick the checkbox.
