Grim Tangle Vines.

When you first enter the Grim Tangle the starting path is covered by vines. When you speak with the NPC (forgot her name) it opens up the way to continue.

But during a run with a friend of mine we where teamed up and entered the zone. Spoke with the NPC and the way opened for me ... but not him. Even after leaving the game and even coming back on a different char (aprox 30 min) it wouldn't allow the way to be opened for him.

We are both the same level, and where at the same part of the same quest as both char had been started at the same time.

We have now left the game for the night and will update this thread should it not allow him to continue tomorrow.
