Sfm looking for models that dont even exist???
So right now im trying to upload a session to the workshop and whenever i try to upload it, it gives me an error saying : unable to find file in mod path models\props\cs_office\light_security.mdl
The thing is i didnt even use such model in my session and if i try to search for it in my sfm folder i cant find it. I dont understand why its doing this
