No Light Bounce / No Light Error : Updated

It's me again with another error! There's a problem in my map where there's no Light Bounce when the map runs normally / first decompile the map has no light bounce as seen below, but when i try to run the map again all the lights disappear and the only way i know how to fix that problem is to copy and paste the map in a new vmf file. I'll be giving you a download of the map and the decomp log so hopefully we can find something thats causing the problem.

Notes:
-There's no pointfile,
-All lights are outside of props and brushes

Decomp Log:

On the second picture, that's just the fences's shadow, double click on the prop and find "disable shadows" and set it to yes. That should fix it.

 

alright

 

Or just turn on material based shadows. Vrad knows how to cast light thru transparent materials. It just needs to be told to do it.

 

I'll do that but what about the other dark shadows?

 

Looks like you just have no light entities in the map aside from the light_environment. Add some light_spots and lights

 

i've had lights in the map but what are light_spots?

 

Light_spot is almost a directional light entity - https://developer.valvesoftware.com/wiki/Light_spot

 

I'll try putting lights outside of the buildings to see if that'll fix the shadow problem
