Ugly baby quest. I have to help her repair a megascope.
Kaer Morhen is a very confusing layout. Searching everywhere I cannot find her.
The quest is selected yet no marker or direction guidance is shown on the mini map.
Restarting the game also does not help.

She's upstairs.

She was not upstairs when I went there. Although helping her was highlighted in the quest list the quest was not activated in the game. I eventually completed the other part of the quest, hunting a forktail. On my return the mini map showed her location, same spot I was previously at. This time she was there.
