Issue when switching from deferred to forward lighting.

You can get the shader source code for the shaders in each build from here: http://unity3d.com/unity/download/archive

Thanks, I tried modifying the shaders, either I am doing it wrong, its bugged or its not related to my issue.

 Shader "DualForward/Self-Illu$$anonymous$$/Bumped Diffuse" {
 Properties {
     _Color ("$$anonymous$$ain Color", Color) = (1,1,1,1)
     _$$anonymous$$ainTex ("Base (RGB) Gloss (A)", 2D) = "white" {}
     _Illum ("Illu$$anonymous$$ (A)", 2D) = "white" {}
     _Bump$$anonymous$$ap ("Normalmap", 2D) = "bump" {}
     _EmissionL$$anonymous$$ ("Emission (Lightmapper)", Float) = 0
 }
 SubShader {
     Tags { "RenderType"="Opaque" }
     LOD 300
 
 CGPROGRA$$anonymous$$
 #pragma surface surf Lambert dualforward
 
 sampler2D _$$anonymous$$ainTex;
 sampler2D _Bump$$anonymous$$ap;
 sampler2D _Illum;
 fixed4 _Color;
 
 struct Input {
     float2 uv_$$anonymous$$ainTex;
     float2 uv_Illum;
     float2 uv_Bump$$anonymous$$ap;
 };
 
 void surf (Input IN, inout SurfaceOutput o) {
     fixed4 tex = tex2D(_$$anonymous$$ainTex, IN.uv_$$anonymous$$ainTex);
     fixed4 c = tex * _Color;
     o.Albedo = c.rgb;
     o.Emission = c.rgb * UNITY_SA$$anonymous$$PLE_1CHANNEL(_Illum, IN.uv_Illum);
     o.Alpha = c.a;
     o.Normal = UnpackNormal(tex2D(_Bump$$anonymous$$ap, IN.uv_Bump$$anonymous$$ap));
 }
 ENDCG
 } 
 FallBack "DualForward/Self-Illu$$anonymous$$/Diffuse"
