Lightmapping + Directional Light not working in forward

Hi

We are encountering an issue where in forward mode when using baked point lights and a real-time directional light that the directional lights light color gets reset to black in the shader. I can easily manually path the shaders but that gets removed every time someone opens it in shader forge so it's a lot of work.

In deferred it all works fine so this is forward rendering specific. in forward base the following code exists

   float3 lightColor = _LightColor0.rgb;
                float3 halfDirection = normalize(viewDirection+lightDirection);
////// Lighting:
                float attenuation = LIGHT_ATTENUATION(i);
                float3 attenColor = attenuation * _LightColor0.xyz;
                float Pi = 3.141592654;
                float InvPi = 0.31830988618;
///////// Gloss:
                float gloss = _Roughness;
                float perceptualRoughness = 1.0 - _Roughness;
                float roughness = perceptualRoughness * perceptualRoughness;
                float specPow = exp2( gloss * 10.0 + 1.0 );
/////// GI Data:
                UnityLight light;
                #ifdef LIGHTMAP_OFF
                    light.color = lightColor;
                    light.dir = lightDirection;
                    light.ndotl = LambertTerm (normalDirection, light.dir);
                #else
                    light.color = half3(0.f, 0.f, 0.f);
                    light.ndotl = 0.0f;
                    light.dir = half3(0.f, 0.f, 0.f);
                #endif
                UnityGIInput d;
                d.light = light;
                d.worldPos = i.posWorld.xyz;
                d.worldViewDir = viewDirection;
                d.atten = attenuation;
                #if defined(LIGHTMAP_ON) || defined(DYNAMICLIGHTMAP_ON)
                    d.ambient = 0;
                    d.lightmapUV = i.ambientOrLightmapUV;
                #else
                    d.ambient = i.ambientOrLightmapUV;
                #endif
                #if UNITY_SPECCUBE_BLENDING || UNITY_SPECCUBE_BOX_PROJECTION
                    d.boxMin[0] = unity_SpecCube0_BoxMin;
                    d.boxMin[1] = unity_SpecCube1_BoxMin;
                #endif
                #if UNITY_SPECCUBE_BOX_PROJECTION
                    d.boxMax[0] = unity_SpecCube0_BoxMax;
                    d.boxMax[1] = unity_SpecCube1_BoxMax;
                    d.probePosition[0] = unity_SpecCube0_ProbePosition;
                    d.probePosition[1] = unity_SpecCube1_ProbePosition;
                #endif
                d.probeHDR[0] = unity_SpecCube0_HDR;
                d.probeHDR[1] = unity_SpecCube1_HDR;
                Unity_GlossyEnvironmentData ugls_en_data;
                ugls_en_data.roughness = 1.0 - gloss;
                ugls_en_data.reflUVW = viewReflectDirection;
                UnityGI gi = UnityGlobalIllumination(d, 1, normalDirection, ugls_en_data );
                lightDirection = gi.light.dir;
                lightColor = gi.light.color;

It's the two last linesthat kills it. Which makes sense if you look at the  LIGHTMAP_OFF define.
