I was walking around the southern part of Fireheart Rise (near the geographical location of Vexa’s Lab) when I was suddenly teleported into Vexa’s Lab. Apparently someone had just completed this mini dungeon, but for what ever reason, this caused me to instantly be teleported inside. I wasn’t in any party, and I was completely alone. I wasn’t even close to the actual entrance of Vexa’s Lab, which is much further north, and quite a distance away. The dungeon had already been finished, and I could walk right to the end (free reward chest for me I guess).
