Hey everyone, I found this bug where if molotov lands in front of a smoke, its effect will make the smoke semi-transparent for a split second giving people free info if someone is behind the smoke.
I believe this is not usual anywhere around the maps, but only in places where the props/player models have the background light, making it possible for you to see their silhouettes. I don't think it works without this background light)
(this doesn't work with CT Incendiary Grenade as it does not have the black smoke around the fire once it explodes on the floor, only T Molotov has this effect)
