Weird lightning effect

[terrorist_hell]

I'm having a problem with my lightmap (or something in that region). It happens when I zoom in with my sniper rifle, almost everthing turns black. I have tried everything from adding/removing cubemaps, lights, compiling full HDR, mat_specular on/off, buildcubemaps, etc.
