My lights do the same as Peri's
Like Tarkus1971, it has always been this way for me as well.
My system seems to only support 3 lights ON at any one time.
If I place 3 dynamic non-flashing lights on the map they all work.
If I place 4 dynamic non-flashing lights on the map only 3 of them work, the furthest one from the player is OFF.
I can have 1 dynamic flashing light and 2 dynamic non-flashing lights without a problem, and all works good.
But once I place a 3rd dynamic non-flashing light the others start to flash as well. Only 3 lights are on at any given time.
The dynamic non-flashing lights that start to flash have an opposite flash state to the 1 dynamic flashing light.
Ie: if the dynamic flashing light state is ON, then the dynamic non-flashing light state is OFF, and vice versa.
Only 3 lights are ever on at the same time, and the dynamic non-flashing lights that do flash are the ones that are furthest from the players position.
Maybe its related to the graphics card?
I may be old, but at least my memory still ....hmmm
