ive got the same problem

I think it maybe something similar to what I got since it's also triggering when I attack a zombie.

. For example, your 2049 line need look like this "if weapon:getWeaponCategories():contains("Spear") then" and the same with 1909. "if weapon:getWeaponCategories():contains("Blunt") or weapon:getWeaponCategories():contains("SmallBlunt") then". And the same with others error that happebs after hit.

how do i fix the error?

"replace "getCategories" to "getWeaponCategories""

Do I need to update the Project Zomboid game file?

i got similar error i think it has to do with Prowess trait , before i added this fix mod it was working as usual, specifically Gun prowess with its ability to not consume ammo at some part. Until i added this mod, this mod fixed antique collector not spawning, but broke Prowess, i dont know how to read error but i assume its an oversight due to B42 change of weapon category

This issue has been fixed!

A pull request was just merged that adds null safety checks for all the weapon-related traits. The crashes were caused by the code trying to call methods (like `getCategories()`) that don't exist on certain weapon types, and the `luckimpact` variable sometimes being nil.

The fix is now available on the GitHub repository:
https://github.com/hypnotoadtrance/MoreTraits

The Steam Workshop version should be updated soon once the mod author publishes the next release. If you can't wait, you can manually download the fixed version from GitHub.

**Affected traits that are now fixed:**
- Pro Spear, Pro Blunt, Pro Blade, Pro Gun
- Martial Artist
- Tavern Brawler

Thanks for reporting the issue!
