ShortPath issue

i have here a surface that i wanted to make a short path with from point to point, but it decides to skip that entirely and hurdle over the open area instead (red curves). it seems to have problems getting all around, so i tried in several steps to see where it breaks. the whitish curves succeeded but it starts breaking when i go even further around.

it seems there is an older open tracker for it RH-40727 @GregArden was assigned, i guess somebody else will have to take over then?
