2.3.0 (Release) Support Placement Issue

[DaHai8 67]

There seems to be a significant Support Placement issue in Cura 2.3.0. It appears to be placing much more support than is needed and in places that don't require any support.

Normal View: Red indicate Overhang areas (right?)

Layer View: Supports just about everywhere - especially where the overhang is almost 0!

This is Thingiverse Night Bat rotated to 150 degrees backward (as instructed) and scaled to 1000% (so its a decent size).

Here's an 80% overhang. Notice how virtually None of the near horizontal surfaces have any support:

Lasty a 90% overhang, which the help text says will provide NO Support (ooops):

Am I doing something wrong/stupid, or is this really horked??

I created a simple arch where each inside segment was rotate 10 degrees and tested the Suport Placement again.

It works as expected with supports being placed according to the degrees specified.

I tested 10 - 90 degrees and they all placed properly - with 90 degrees having no support and 10 having everything supported.

So apparently Cura is just going Batty (sorry) with that model's supports.

P.P.P.P.P.S: Cura 15.x supports the bat properly:
