Hello!
I’ve been doing some missions with my alt and i got to 62 lvl mission “Forging The Pact”. It seems to be bugged really bad. Invisible walls, graphics glitches. I was unable to finish it because “wall” kept me 10 feet from npc. I recorded this issue so you can see it by yourself.

PS: Few months ago i had other bug in the same mission. Asuran researcher didn’t want to blow up rock wall after killing waves of risen.
