Cubemaps and light error/bug?

Okay, so I'm here with a little problem that (maybe) is something I did wrong because I'm new into mapping to source (usually I mapped a lot in gldsrc), so.. the problem is that when I was working in this map everything in the lights were fine until I build the cubemaps. Then the lights started to look like this


I know that maybe is something that I did wrong, so pls tell me what's and how I can fix it to keep learning how Source works.

Thanks for waste your time reading this

This is a screenshoot (in hammer) where the others were took in game, as you can see the cubemap is not too close of the cubemap...

oh damm, sorry Werewolf, I didn't see that, now i fixed it :v

Oh well, today I tested my map again and that thing disappeared, so thankis anyway. I
appreciate your help
