I don’t want to give too many details, because this is a big problem and could be a huge exploit in the wrong hands.
While simply running around one of the borderlands maps, I used a teleportation skill to go faster and suddenly I was under the map, swimming. At first, I thought it was awesome that I could see everybody running above me and killing each other on the map, but after a little exploration and a quick test I ended up breaking back into the map in an enemy keep on the first try.
I reported it twice and got a couple of friends to do the same. It’s been about a week now, and I know it’s not easy to go through all the bug reports and correct the important ones, but I REALLY think this one needs to get done fast. It’s completely reproducible every time, and it’s only a matter of time before someone else stumbles upon it like I did.
If a dev or anet employee sees this, please contact me in-game and I’ll give all the details (or just try to find my bug report, where I explained in detail with a screenshot).
