This error is constantly spammed while in-game.

what are you holding when that happens?
That error is saying that your holding an object that doesnt exist.
more specifically, whatever is in your hand doesnt have the capability to call the getCategories() function. which all items in zomboid are supposed to have.

Subject: Bug Report - Crash when holding any item in main hand (ISOLATED TEST)

Mod: Even More Traits [b42]
File: LazoloMain.lua
Issue: Game crash occurs every tick/second when holding ANY item in main hand

Testing Environment:

✅ Tested with ONLY Even More Traits mod and Stat Tweaks Lib
✅ No other mods enabled

❌ Bug still occurs - confirming this is an issue with Even More Traits specifically

Error Details:
text

ERROR: ExceptionLogger.logException> Exception thrown
java.lang.RuntimeException: Object tried to call nil in GetWeaponPerkLevel at KahluaUtil.fail(KahluaUtil.java:101)

Problem Description:
The error occurs in the UpdateHeldWeapon() function which is called every minute by LMinuteUpdates(). The function calls GetWeaponPerkLevel() with Player:getPrimaryHandItem(), but this fails when:

Holding non-weapon items (wooden plank, rolling pin, etc.)

Holding basic vanilla weapons (starter pistol)

Holding ANY item in main hand

CONFIRMED: Issue persists even with only this mod enabled

Affected Functions:

GetWeaponPerkLevel (line ~31)

UpdateHeldWeapon (line ~2420)

LMinuteUpdates (line ~3077)

Steps to Reproduce:

Enable ONLY Even More Traits mod and its required dependencies

Start new game or load existing save

Pick up any item (weapon or non-weapon)

Hold it in main hand

Error occurs every tick/second

Expected Behavior:
Function should handle non-weapon items gracefully without crashing.

Critical Finding:
The bug is not caused by mod conflicts - it occurs even when only Even More Traits is active, confirming this is an internal issue with the mod's code.

`getCategories()` for weapons was replaced with `getWeaponCategories()` in 42.12

I got a comment mentioning this mod and person didn't reply for some time so I decided to come check, hope that helps!

It did work. There's just two files named lazolomain.lua

It did work. There's just two files named lazolomain.lua
everything in the "42.0" folder is for build 42, everything in the "media" folder is for 41 and older. this is just how the file structure was changed when B42 dropped.
