Guild Wars 2

As a mesmer, using staff 2 (phase retreat) after being trapped in a crystal causes the player to teleport out of the crystal but remain frozen for about 15 seconds, even after the crystals all explode.

That skill has problems in general, teleporting back into the terrain sometimes. (Right next to the waypoint in Garden of Ilya if any devs see this)

Yeah, I’ve experienced this with my mesmer, too.
But if I remember right my ranger sometimes has similar happenings at the Claw. She should be locked in the ice crystal, but can run around until she can use her normal skills again (as long as she shouldn’t run around she has the skill that you have to break free from the crystal).
