Idk why this happens but for some reason when I add an addon like a gun or a soldier skin/model, the game says I'm missing a file. For example, I add a RU soldier skin to a map (that I already have on a map that had no issues whatsoever) and when I load the map It gives me this error message. I tried looking this error up but no luck. I do not know if this is a texture for a dirt path or a tracer but this is my first time having this kind of error messages.
I apologize if this isn't the right place to ask for help but idk where to post this.
