I know there was a mod that gave you a pair of greaves which had a script that would kill any cliff racer within a certain distance of you. Just using the tgm console command might fix everything for you, unless the attacking still bugs you or you want gauge combat difficulty or something. You could also go into the editor and set all the generic cliff racer id's to 0 health. Still, do you really want to run a mod that your mod isn't dependent on while checking for inconsistencies? Especially a mod that effects cells your mod uses.

This mod supposedly removes all cliff racers...
I've never ran it and can't run MW at the moment.
That mod doesnt work, i even tried creating a new game (must be that mod i tried before..), there's still a lot of cliff racers. Can't believe 5 people have giving it a thumbs up, did they even try it? I dont use any mods except my own texture / models mods so i dont think its some conflict..
And yes there's no problem using a mod like a cliff racer remover etc for me when checking for inconsistencies, i'm not doing mods with scripts or anything like that, just models and textures.
Im not any good at the editor, but if there arent any working cliff racer removers out there i guess i'll have to take a look at it..
