Problem with lighting during the night

I am having problems with lighting all over the map.
While I am driving (this happens only at night with the street lights on), some of the street lamps, are turning off when passing below them.
Other players may or may not counter the same problem as me.
This problem is nothing, and I could come over it, but then…

Now this is a problem.
This can be fixed, if the player goes away from the hospital, and then comes back, but still…
I am trying to figure out what is the problematic script causing this, but I had no luck.
If anyone has any suggestions on how to solve this, I would appreciate it.
I have already tried a lot of things, like disabling and enabling geometries, but I had no luck on finding out what is causing it.
