Gonna start off with I have no clue what I am doing. ChatGPT helped me put this together. It's not a fix fix for the mod. But I've played a little bit with this "fix" and I haven't come across any game ending issues with it.

So first off, find MA_BodyLocations.lua
Should be here:
steamapps\workshop\content\108600\3512993822\mods\Support Corps\42\media\lua\shared\NPCs

Open the MA_BodyLocations.lua using Notepad++ or whatever you use
-------------------------------------------------------------------------------------------------------------------
Events.OnInitWorld.Add(function()
local group = BodyLocations.getGroup("Human")
if group then
group:addLocation("MALeftArm", ItemBodyLocation.LEFT_ARM)
group:getOrCreateLocation("MALeftArm")
group:getOrCreateLocation("MARightArm")
group:getOrCreateLocation("MAHAZMAT")
group:getOrCreateLocation("CarrierVest")
group:getOrCreateLocation("Cloak")
else
print("ERROR: Human body group not found.")
end
end)
-------------------------------------------------------------------------------------------------------------------
Copy that block of text, IN BETWEEN the lines, don't copy the lines.

Then inside the MA_BodyLocations.lua press Control + A to highlight everything, then press Control + V to paste that block above into the file, then of course save it


There was some restructuring of files, meaning I had to move some of the files to other spots. I am still currently trying to find the instructions that I followed by Chat to do so.
If the file MA_BodyLocations.lua is NOT in that location (Support Corps\42\media\lua\shared\NPCs) then that's where it should be for this fix


If this does not work, please kindly tell me in the comments and I will continue to dig back through Chat to find my exact steps. Again, not a coder/modder so I can't guarantee that this will fix it for you. If it doesn't work, I apologize.
