Bomber plants Tempest/Stagger/Veiler/Shivermist ---> No vision of the bomb being there ---> Status inflicted on me (though there was no indication of the bomb blasting) ---> Die and rage revive.
Cycle through over and over.
I'm really not sure if there was another thread with the same problem, as it's easily noticeable to players who don't have protection against that certain status. So my apologies if I'm repeating anything.
This isn't a bug appearantly.
If ye have applied Cull Transients, as Hector-Uribe mentioned, it could affect some of the bomb mists not to appear at screen, including some Clockwork monsters such as Zombie spawning has lost it's graphics of coming out from the grave.
Otherwise, ye may be having connectivity issues(which it happens SOMETIME, even when ye are very smooth as well), the mist does not appear at some rates, causing a very bad luck struck down to ye. 0.0
If ye can't see Nitronome bomb or Dark Briar Barrage blast even it's at yer screen... with every step I mentioned above done... that could be a bug. if ye're lagging there's a small chance ye can't see the blast, or will(but the blast will jump out from the radius of the bomb's fixed position).
