After clearing some of the rooms we had trouble opening the gate, even the room clear the gate was still blocking the gate, one of my party members went all the way up and found some tiny mobs, i don't remember their names, but they are similar at the ones the bosses in DDM summon and they follow you, just like tiny dragons. After he went to the first room he kill the mobs and the gate open, unfortunately i don't have an screen shot to show the glitch, but i guess people is having this problem and so far this is how you can fix it till an admin take a look on the issue. Anyone is welcome to post a picture of the glitch in case you know what i'm talking about. Not to mention that there's other players having other kind of bugs, would be cool if you share them on this post Thanks for your attention! Cheers!
