Thanks! That fixed it : ) Basically, with the pulse on, the light image disappeared after one second when the actor entered the map. It looked like an eye closing around the light if that makes sense.
The eye closing problem is basically because the pulse setting old default value is 1 scale, but now it is 100 (percent) scale. So the old light will get pulsated into 1% their original radius. You can just disable pulse or set it correctly to, like 120.
I tried it at 120 and it was still "blinking." I wasn't really using it before, so it's no problem to turn it off. I've included photos if you want to look into it, but no issue otherwise with pulse.
