Poison Bomb bugs

Describe the problem. Be as specific as possible!: There are 2:

• DC bug: Within a specific duration after throwing a Poison Bomb (NightWalker's skill), you are subject to immediate DC if you either CC or die. The severity of this issue varies for different users, some (like myself) get sent back to the log-in screen while others may have their Maple completely shut down.
  
• DS bug: Same scenario as above, but if you cast Dark Sight instead, your DS-state will be cancelled without notices or even hints.

I'll try to capture some screenshots of when I DC later, hard to do with DS though.

I think this problem is well-known, but I have yet to see it listed here so why not.
It's a bother for when you Poison-train on CGs and DC every time you 2x exp buff. Or it significantly slows down the potential training speed (not saying we don't train fast enough already).

This glitch is very annoying
Good to know Im not the only one suffering cause of this.

This is not a bug, when you throw a bomb you cancel out of dark sight, if you activate it right after again before the bomb hits it will deactivate again when the bomb hits the ground.
I experienced this also and thought it was a bug, but it is not.

So the skill has 2 'activation animations' so to speak? That actually makes sense, just very little. But it does explain why the 'specific duration' for case 2 seems to vary.
