Guild Wars 2

Location: Rellaitus Canyon, Blazeridge Steppes, Ascalon.
Problem: When hitting a skritt trap I fell down and did not get up for about a minute, then I could not move or jump. I could swing weapons, but not move from that spot, I relogged and it hit me again and did the same thing, I finally managed to carefully get out of the area.

Next time just use a waypoint, if you could recreate the bug, get a screenshot and then send it off to support in game or post it here it would be more helpful, who knows how many traps are in that area.

Let me guess: you were not able to even turn your character, so it was basically like a never-ending immobilize without the accompanying condition icon. There are several things that can cause this kind of bugged behaviour, but those skritt traps are definitely one of them.
From the other occasions I had this happen to me I get the impression that the bug occurs when an NPC or object is killed or destroyed just at the exact moment when he/she/it uses an immobilizing power on you. If it is an object that basically detroys itself when activated, like, say, a skritt trap, this happens on a regular basis.

Try to use any moving (charge, leap, blink) skill or /dance /sit /sleep emotions, usually you can get out of this immobilize state without reloging or teleporting to WP this way.
