XP Multipliers Conflict – Error with Fitness/Strength XP when multiple traits are active
Disclaimer:
This is a quick and dirty patch I made to fix a specific issue in the More Traits mod.
I’m sharing it here in case it helps others, but I’m not the mod author.
If you want a clean, official fix, you’ll have to wait for the mod owner.
Please don’t come complaining to me – this is just a "works for now" solution.

🛠 Issue
When multiple traits that modify XP are active (e.g. GymGoer + spec* traits), gaining XP in Fitness or Strength causes:
    Errors in the console.Incorrect XP values.
  • In some cases, the game might even crash.

🔍 What I Found
The original code in the functions Specialization and GymGoer doesn’t handle multiple XP multipliers stacking properly.
Variables like skipxpadd and hardcoded if/else blocks cause conflicts.

✅ Quick Fix
I created a helper function GetXPModifier(player, perk) that calculates all XP bonuses dynamically.
I then patched Specialization and GymGoer to use this function instead of their old logic.

📜 How to Apply
    Go to your Project Zomboid Workshop mods folder.Open the MoreTraits.lua file (usually under C:\Program Files (x86)\Steam\steamapps\workshop\content\108600\1299328280\mods\More Traits\42\media\lua\client).
  • Add the following function near the top (just above AddXP):

local function GetXPModifier(player, perk) local m = 1.0 -- GymGoer bonus if player:HasTrait("gymgoer") and (perk == Perks.Fitness or perk == Perks.Strength) and player:getCurrentState() == FitnessState.instance() then local gymMod = SandboxVars.MoreTraits.GymGoerPercent or 200 m = m * ((gymMod * 0.01) - 1) * 0.1 end -- Auto-detect spec* traits local specMod = (SandboxVars.MoreTraits.SpecializationXPPercent or 75) * 0.01 for i = 0, player:getTraits():size()-1 do if player:getTraits():get(i):sub(1,4) == "spec" then m = m * specMod end end return m end

  • Replace the body of Specialization with:

function Specialization(player, perk, amount) if perk == Perks.Fitness or perk == Perks.Strength then return end local finalAmount = amount * GetXPModifier(player, perk) AddXP(player, perk, finalAmount) end

  • Replace the body of GymGoer with:

function GymGoer(player, perk, amount) if player:HasTrait("gymgoer") and (perk == Perks.Fitness or perk == Perks.Strength) and player:getCurrentState() == FitnessState.instance() then local finalAmount = amount * GetXPModifier(player, perk) AddXP(player, perk, finalAmount) end end
🎯 Results
With this patch:

No more XP errors with Fitness/Strength.

XP from multiple traits stacks correctly.

The mod remains compatible with future traits that start with spec.

💬 Final Note
This is a quick workaround, not an official fix.
If you want to revert, just restore your original MoreTraits.lua file.

Going to try this out, my game keeps deciding I'm not allowed to become stronger and crashes out my game every time I try to exercise. The problem you explained sounds like mine so here I go to "Code" for the first time :spiffo:

Edit: It worked, thank you so much! You made that super easy.

Maybe I'm stupid but I think I must be replacing the wrong code.
Currently I'm swapping everything between and including

function Specialization(_player, _perk, _amount)
local player = _player;

and

else
skipxpadd = false;
end
end

any help appreciated :steamthumbsup:
