The thread title pretty much describes the bug. I'll trigger a particular trap (a trapped sarcophagi at around the midpoint of the room) in the Copperlane Catacombs and the visual and audio effects will just endlessly trigger, causing a drastic drop in FPS. The trap itself seems to have no effect, sometimes I'll get a combat log notice that the character was interrupted but otherwise no attack is made/rolled and no damage is ever dealt. The bug happens every time this trap is triggered even after shutting the entire game off and loading a save. I haven't looked to see if other traps in the area do the same thing, although I know there have been other traps I've triggered on this playthrough that weren't bugged like this.

 

Here's a video of the bug in action:

 

Yea I've had this bug twice. One at the Wael Library but the other one I've forgotten where it was.
