Quote from TheGumaOne of your light entities has "Appearance" setting changed. It is a known bug in CS:GO SDK, if you change "Apperance" setting to anything else other than default it would cause broken shadows.
For those who don't know, "Appearance" setting is used to change how light flickers ETC.
yes, this fixed it, i had i light that was flickering. thanks for your help. but is there a way to have flickering or pulsing lighting in csgo that dosent have this effect?
i checked and i dont have a leak anywhere in the map, i tried to load pointfile and it just tried to open a file (no red lines). i remade the skybox, changed the lighting and recompiled, but still weird shadows 
so im quite new to mapping in source, i was making a small map to test some things and i found a weird square shaped shadows, i have no idea what causes them or how to fix them. help
Im looking forward to see how this turns out, it looks like old mirage and inferno. lots of potential. but the ramp leading onto the a bomb site should be made into a shorter staircase or something.
you should change the groud texture to some sort of concrete or tarmac blend and maybe a few more lights inside. apart form that it looks pretty good 
thanks for the feedback (anything helps me at this stage). I added the cubemaps and a bit extra lighting, here are some new screens.
I was wondering how to get rid of the bad shading around some props (eg.the rubble and plants) also how to make the red spot lights look a bit more natural
i havent played it yet, but looking at the radar, a few more entrances to the bombsites would (in my opinion) would make it a bit more competitive.
so yea, i have been lurking on the forums for quite some time now, so i finally made an account so that i could get some feed back on a map i was working on.
this is the first map i have ever made ever(excluding little big planet 
) i taught myself the basics of the sdk and started working on this small, fast paced defuse map. i am aware that i went with the most generic theme possible but this map is really just an experiment for myself to see what mapping was like. Two months later I have started adding some details to the map and i think its coming together pretty well .
I am looking for any tips to help me in the future, so any opinions you have or tips for me, please tell me especially towards lighting.
(also if you could give some nae suggestions XD)
so here are some screens
