I don't actually have the game, but I have watched a metric fuckton of streams of it. And every time I think "all right, NOW I'm getting it" something ridiculous happens. An AK with all the attachments just despawns and is gone. A guy makes a narrow escape, and a minute later is suddenly rubberbanded back to his original position and gets killed. Someone runs away from a Zombie who is 50 meters behind, randomly swings at the air - and the dude drops dead. A fully equipped guy suddenly just falls over dead when walking down a flight of stairs. An item is visible in the inventory, but can't be used and interacted with. That is, until the dude throws it, it hangs in the air, then he punches a wall and it falls to the ground.
And all this happens so often that it cures me of my "I wanna play this too" impulse every bloody time. Because I would probably throw my monitor at a wall. I play CS:GO already, there's only so many games that regularly make me rage I can tolerate.
