Velious Traps -- questions

[Aeolwind]

From my memory:

-They were actually invisible NPC's, even after triggered, that used proximity to trigger effects.
-Many of the effects were 'target' effects, so using 1 person to activate the trap and the others run passed while it was recycling didn't work. As each entered the radius, they'd get their own joy buzzer.
-When you pressed locate traps it spun you to point at the trap
-When you hit disarm, it affected a radius around you, fairly small
-Disarm 'killed' the NPC and it would despawn.
-Respawn time was not consistent. Some were 6 second respawns, some 1 minute.
-Some traps when triggered you could see the name of the NPC: 'Dispel Trap', 'Insect Trap', etc a brief moment before they despawned or activated again.
-They were immune to AE's from players, but could be hit by other traps AE's activating them.
-They did not always show on track. Some did, like animal or insect ambushes.

I do not remember their interaction with Sneak/Hide.
