Toon Shader Not Working With Multiple Spotlight Shadows (Pro)

Hello all,

I've been working on making this toon shader from scratch. I have manage to get it to look great! However, it can't get shadows from multiple spotlights(it does work with directional), D:

What it looks like:

 Shader "Custom/ToonShader" {
     Properties {
         _MainTex ("Post Image", 2D) = "white" {}
         _RampTex ("Post Image", 2D) = "white" {}
         _Strength ( "Additive Strength", Float ) = 1.0 
         _TintColor ("Tint Color", Color) = (1.0, 1.0, 1.0, 1.0)
     }
     SubShader {
         Tags {"Queue" = "Geometry" "RenderType" = "Opaque"}
         Pass {
             Tags {"LightMode" = "ForwardBase"}
