mapping help

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...

I am currently looking for a skybox for a map I am adopting and I wanted to know if you guys like day or night maps due to the only non-event night koth maps are koth_king and koth_probed. Thank you for your help BlitzVS
