I'm unfamiliar with many of these, but I do know that Ykara's Expanded Prosthetics and Organ Engineering mod patches the path of prosthetic textures. This could be the issue. If you backed-up your save and loaded it without that mod, could you check if it works then?

I've run into the other error you mentioned when I was originally writing this mod. It happened when a simple finger with an unsupported material was installed. What materials were the fingers you tried to install that disappeared?

I'm not sure, unfortunately. I know one was jade and some where steel. I'll try doing it without those mods.

Loaded up a new colony running only this mod (+ harmony and mod loader) to check for mod compatibility.
Fingers work, Toes just vanish on use.

System.NullReferenceException: Object reference not set to an instance of an object
at ProstheticDigits.Recipe_InstallArtificialBodyPartWithStuff.ApplyOnPawn

Essentially it looks like your HediffDef and RecipeDefs are missing for all the simple toes. i.e. no definition then exists for the installed material based part.

So I got it working..
I copy locally, open up BasicDigits.xml copy and paste your FingerDefs but replace Finger with Toe (except continue to use the same AddedBasicFingerBase parent) and it seems to work.

I guess this would also the be issue where the material is undefined for fingers, except this is missing even the basic materials for toes.

Nice find.
