Since the update, my area measurements have been messing up when I try to add a curve control point while measuring. I hold ctrl + click and drag and it almost always reverts back to a straight line when I release and adds a point where my cursor was holding the curve.
Also, the lines/area disappear completely if I move the cursor to a place where the area would intersect itself. This makes it difficult to measure complex shapes, which I am regularly doing.
As a side note, I think the thicker placement line makes things harder to accurately place.
