Pinging a player in team chat will send a notification sound to the target player regardless of if they're in your team or not. A few of us were having some "ghost ping" sounds coming through with no text in global and pinned it down to speaking in Team. Additionally, a spicy detail to this, the more @'s you put into your chat, the LOUDER it gets for the person on the other end, leading to ear-splitting ghost pings from unknown parties

Double clicking the bag when attempting to teleport will successfully teleport you and charge you twice. I recently bought a teleport using in-game currency, and accidentally double clicked it. I was charged twice, once at 150cr and another at 200cr
