Glitch with "A Present for Bianca"

I have the same problem. I just updated the game with the first patch and when I got to the wartable i saw the quest was complete. When hovering over the quest the mouse info shows the quest as "busy" in red despite it having the exclamation mark over it.

When I click it I get that same screen. Back button is greyed out and game continues but the scroll is empty and I couldn't exit the screen in any way.

Edit:

I played a bit more. Now the red busy is gone, but the empty scroll still appears and effectively stops the game forcing me to close the process and restart the game.

Have the same problem with this as well.

On my first playthrough, the operation shows up, and without doing anything, Leliana had already taken the operation even though she was already on another.  So I thought that was normal and Leliana was just doing a special favor for Varric since I had Leliana do most of the Hard in Hightown operations.  Nothing ever came out of that operation in the end.

On my second playthrough I was able to do the operation properly and when it was complete I would get the blank scroll.

I'm playing on a PC, and ahve a similar problem.  

when I initially clicked on "A Present for Bianca", the scroll opened and I had a chance to assign the mission to someone, but I already ahd Leliana doing a mision, so I closed it.  Later, when Leiliana was available, I tried to open it, only to get a blank scroll, and everything else grayed out.  Had to use Task Manager to close the program.

After the patch, the mision showed as "Busy", even though I hadn't assigned it to anyone.  My next visit to the War Tabel and is showed as available.  But when I select it, the same problem of the blank scroll and everything else grayed out.  

Extremely frustrating.

same on PC version scrol comes up blank and game freze, music and arrow are movable but you cant go back or anything

Same problem, XBox One.

same problem, PC.

Click on "a present for bicanca" totem, then a scroll opens with no writing, and that's it! nothing more happens until forced to ALT-F4 out of the game.
