Valve's update caused players to see through smoke

After the "Mission Impossible" update that was released on May 7th, the game experienced a new visual exploit, where the player models became visible through the smoke under certain conditions.

The said conditions, specifically, included a molotov thrown behind the player model, which allowed the players sitting inside a smoke to see the player model even through it. The bug was shown in a video released by Eric "zuac" Zuccaro.
