I'm not sure the new name of the area, however, i was collecting skiulcap and noticed one of the plants was placed on the trunk of a tree that could not be collected. I tried gathering it from all angles, unfortunately it failed to be picked.
Now it might have been a prank from a GM to see how long I'd keep at it before resigning to the fact it just not going to happen (nice one) or it's definately a bug.
Cheers,
