Sorry for putting this in wrong place before. I got all the way thru Tolvalds Cave and down to the Crossing where there is a rock fall blocking me from getting to the crown. I used the console oommand tcl to go thru the wall and it worked and told me to get back to Vex. but when I got back to Vex she told me I did a good job but did not take the Crown or Stones. Any ideas how to finish this?
Are you using the mod that adds quest markers for the stones? If so, disable that mod and then load a save from before you speak to Vex (with crown & stones in hand). It should then complete correctly.
