Guild Wars 2

So, I was walking around Gendarran Fields when suddenly I dove into water. The first thing that came to mind was: Was there water here?
My boyfriend said “No.” But I was underwater. So he looked around and where was I? Nowhere to be seen.
I was under the ground, in water, so I swimmed to the nearest lake in a attempt to emerge, but I was under the water, inside water.
It was a really nice view, but I thought I should alert to future bugs like this.
Logging out and logging in fixed the problem. And in addition I now possess a nice screenshot of a upskirt.

You’d only be able to get back above ground the place you fell into the ground, as that’s where the hole was.

As for the water, normally levels and maps are surrounded by water in games like this so that if you need water for a portion, you just dip the map below that level.
