Somehow one of my shades is missing: both Formello and Silvar have the Shade of Ice. If I kill it in one of the towns, both towns are happy and shade-free. But Correlea only counts it once, so I cannot close the quest.
Which shade belongs where? In Blosk and Dharmon I have the Shade of Terror.
My oldest save is in Mertis - already both towns had the Shade of Ice but I didn't notice...
I completely avoided the shade in Formello, so I never got the message "You are near what was once a lovely park".
In Silvar on the other hand I met the shade , for the shade experiment quest - sorry, I don't remember what shade I fought. I guess the Shade of Ice because when I get now near it, there is no introduction pop-up.
