As the other person that was having the problem, I found that deleting

rawfile,maps\_zombiemode_weapons.gsc

from the csv made it work.

Yep, it worked, thanks a lot everyone.

Hey guys. I can't believe that slowly but surely, BO zombies is becoming moddable... So I've tried this tutorial to change a weapon's stats, and nothing else. The only file in my mod is m1911_zm, which I tweaked to make fully automatic and start with full ammo, as a simple test. I followed the steps...
