Thanks for creating a discussion, It's strange since my vanilla game is working fine with just the Archotech mod installed. Have you tried testing the mod with nothing else installed? It's probably a mod which deletes certain classes or overhauls some part of bionics.

Can you send me your mod list? I'll go through and test to see which one it is

I am seeing the same error. I think either sparkling worlds, or glitter tech add implants, I think one might have a brainpal implant that might be bumping into your mod,

alright I'll install both of those mods to see if it messes with it

Both of those are fine, no problems

I had the same Issue but magically it got fixed. This is what I did:
-Disabled all mods except HugsLib, JecsTools, and Archotech
-got many errors back so I quit the game
-Game said it was still running so I logged out my User on windows
-logged in again and started the Game agein
-no errors anymore
-added all mods, ca. 10 at a time
-never got an error
-all mods back on and now it seems to be fixed

Very strange

I'll try a restart when I get home tomorrow

I am still seeing this error:

I will try a full reboot and retest it.

Everyone here, I managed to reproduce the error. If you have a prosthetics mod of any kind or even some random mod, try moving archotech expanded higher in priorities. I get the error if Archotech is underneath both epoe or RBSE, so having it above those mods should resolve the issue. I'm still trying to find ways of being able to make it lower in the order, though. Thanks for all your help and continued support!

Got the same errors and two more:
{ССЫЛКА УДАЛЕНА}https://git.io/fxr46

your mod is the first in the load order that got anything with medicine/implant's and prosteses to do.
keep up the good work ^^
