The other day, I was running my rogue around Velks to look for collectibles. He got stuck in the ice, not once...but twice! The first time, it forced him to duck so I couldn't even camp or gate out...had to call him out with a mage. The second time, I was able to use an anchor to gate out. Both times, it happened on the various ice formations on the ramp section at the start of the zone. The first instance, I was climbing up on top of an ice column to get a better look at an area, and I just "fell" into the ice. The second time, I was on the walkway going around a corner, and it was like the ice just grabbed him and pulled him inside. The rogue was a gnome.
