Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Lady in the Lake quest line bug?

So I am at a loss here and not sure how to proceed. I am currently doing the Lady in the Lake quest and I am in the Hibernian Cave. I am trying to get through the the 2nd gate to resolve the Lady in the lake quest where she is on the ground. I have found the key that is buried in the mound and unlocked the lever, but the gate will not open.

You need the Teleportation skill from the aero tree (or substitute it with a scroll) or the scoundrel skill Cloak and Dagger. I guess there is also another way but I'm not aware of it, maybe through a pyramid and teleport to it; man-at arms skill Battering Ram could work also.
