This is the second time this has happened to me. I'm doing a quest in a tomb and you get to the end and for some reason it says you can't use that door or there is an visible wall because you did not complete the quest exactly.

The first time I went in a door, went out it, tried to go back in and it said I could not use that door right now. I had to dump the quest and start over.

This time On Ancestral Adversity I went through the entire map. I must not have "entered the tomb of the matriarch" properly and went out the door taking me
To the beginning. Ok, I'll just start going back around the map. I got the the floor puzzle, floor lit up, gate down, walk through the down gate through the room... invisible wall on the door way. I should be able to go back where I came. And there was another player with me who could not get through either. Oh look, that player could go though? Why not me?

Why are these quest not allowing full Map access start to finish? Where are the safe guards to prevent this from happening? Not everyone is point A to
B. People get turned around.

Maybe it's just me but the white markers also seem to be miss leading at times or non existent.

I guess I'll dump this quest and try again some other time.
