FPS drops / Siren necklace

[Shîro]

Hi,

Since last maintenance I have HUGE FPS drops to the point of "program not responding" when bosses use the "chain" combo in the middle of monitor. Before wednesday I barely had 10-20fps drops, now It freez my whole game..

Siren necklace have duplicated ID, have two of them in inventory and can't stack them, one of them has 2 stacks one has only 1 but doesn't even shows as that I own 3, just 2 and 1.

About the siren neck, it happens to me too since the start of the game. I think it happens with every jewelry of the 24 man dungeons. (Pirate and Siren)
I think the Pirate or Siren jewelry from 24 man vaults stack separately from the 4/6 man ones. I want to think its a bug, because they have the same name, effects... everything the same, but oh well...
