So discovering I couldn't prerform all the same operations on my Ferian race pawns as my Humans, I did some digging and discovered someone who had the same problem with the "Lapelli Race" mod and found a fix.

If you put <humanRecipeImport>true</humanRecipeImport>, inside the <generalSettings> tag, you no longer even need to manually make prosthetic mod patches, as that will take care of it for you automatically.

You can apply the same thing to your Ferian Race mod as well.

And, well, that worked! Does have one slight issue, it seems whatever method the Author is using overlaps with this, so now I have two tabs under operations for installing some things like Bionic arms, but modded items like rebuilding a nose are possible!

To do it yourself (note: Likely will be broken when the mod author updates the mod) you need to fiddle with an XML file, as a result I recommend just in case making a backup save. Shouldn't be possible to cause real damage, but best to be safe then sorry.

First, goto \Steam\steamapps\workshop\content\294100\1611790118 (this is assuming you are using steam workshop, otherwise it will be in the Rimworld standard mod folder.)

From here select the version of Rimworld you are playing, then the Defs folder, and lastly ThingDefs_Races folder.

In my case it looked like: \Steam\steamapps\workshop\content\294100\1611790118\1.2\Defs\ThingDefs_Races

The lone file here is what we are after, open it with notepad (or if you are fancy, Notepad++) And find the line with "<generalSettings>" and create a new line under it.

Here type in "<humanRecipeImport>true</humanRecipeImport>" then save the file, and launch Rimworld.

In the off chance this breaks something, you can always delete, and reload the mod of course, but I hope this helps some folks out!

Also Bichang, if you see this, I love the mods and thank you for your hard work!

Edit: An update to deal with the duplicate "Add bill" entries.
On the bottom of the Ferian_Race.xml file there is a list of entries like '<li>RemoveBodyPart</li>' all within a <Recipes></recipes> block.
Just take everything there, and delete it! What we added before does the same thing, only with far more flexibility.
