Guild Wars 2

It happened to me like 5 times, that i ported / glitched myself out of the map / through the wall.
Most of the time its when i use some kind of teleport as mesmer (e.g. illusionarry leap -> swap; 2hStaff 2nd skill (forgot name ^^) ), that i am stuck inside of walls or even go completly through them.

here are some examples that i had:
first thing was in the sPvP map “Battle over Capricorn” (or what its exactly called, anyways the map with the sharks ^^ ) an enemy was standing directly @ the wall behind the capping point “Beach” i used illusionary leap and swapped with my illusion and i found myself behind the enemy & behind the wall, unable to go back to the map.
so i just rand further back and fall into the ocean under the map i was unable to go back up, but fortunatelly a shark appeared and nomnomed me

malchors leap: i just used the 2hstaff skill 2 where u port yourself back a bit and leave a clone at your original position. i used it and found myself again in the ocean under the map (it was a terrain with no hill etc i just dropped under the map.
luckily i found a staircase i could stand on and blink myself back into the map

80 dungeon story mode: again with the 2nd staff skill i managed to port myself into one of the cannons on the flying ship. i was unable to move, but ported myself back into the map again with the same skill (staff #2)

hope it kinda explains what happened and u find a solution for it, cause its really annoying =)
