So i have noticed on isle (on latest bugtest) when i once spawned that my screen is flashing like when you are looking at DOT grenade. I spawned in BE base and they were using DOT grenades in NF base. So the effect can be seen on very large distances. Didnt tryed it again after this... We should test that also in next bugtest.
It's just a testbed at the moment, using a random particle. I don't think that will happen once it's set up properly with the new particle.
