Today my guild and another guild has tried to do the guild puzzle, but when we got to the “Ascend the frozen slopes and force your way through the sealed gateway” event, we got blocked from what seems a bug- We kept destroying the walls, but when we tried to go past them, we got teleported back to the powder keg. We kept trying untill the timer got to 3 minutes. We reported the bug already and i hope this post helps.
Sorry for my bad english.
