Hi Michael,

>>>One other thing you can do to work around this problem right now is to dice up the edge curves into some smaller pieces, like say 4 sections instead of one long edge.

Doing that actually shows an overlapping edge. I sliced into 4 quad, then made blend. The top left blend was incorrect (on the scale used)
