Yeah, that spot had a tangent difference of 0.68 degrees between the different pieces.

Not much, but enough so that the edges had enough of a gap to not join.

Yes, I think eventually I'll try to package this up, probably when there are object properties for the selected object, possibly this will be a changable property on selected points in the same properties UI. It will be a while for that though.

In the meantime you can do the equivalent of a change by inserting a new point and deleting the old one.
