up! I'm having a issue which the event is never ending, which causes to all zombies know my location, I wonder if i could turn the mod off in my save, but I'm afraid to lost my save

This is a late reply but for those still wondering you can modify the mod in sandbox options in the admin menu by using /grantadmin on yourself. Otherwise just remove the mod in the mod menu. The mod is safe to add to a game and you can remove it while probably not messing with anything
