Guild Wars 2

So im in Kessex falls (I think its called) in the underworld server near the large centeur camp on the left hand side of the lake.

I was mining an iron rock and then got hit by a catapult, the next thing I know my character was flat on its stomach but I could still move around and jump. After a minute or so it fixed itself.

A lot like the pre-release sit down and jump bug.

Happens for me as well in alot of different positions.
