Steps:
I was exploring through Adoulin when I zoned in to Morimar Basalt Fields from Moh Gates. When I zone in to the area, it appears as normal and I am able to run forward for approx 6 seconds. I am able to target the Goblin's Footprint on the bend in front of the zone line. As soon as I get within about 5 steps of it (and the rest of the zone), I get zoned back in to Moh Gates. This is happening continually. When I run backwards instead of forwards, I am able to run back passed where I zoned in to the area and run through a tunnel to a point where I get a dead end and can see a missing wall (can see the sky, mountains around and just a grey floor).
I have shown this to a GM in game who has kindly advised to raise this via a bug report.
