How to reproduce

1. Load the model linked below.
2. Slice at a .16 layer height.
3. In the Preview pane, scroll to layer 69.

Pictured is layer 68, showing nothing under the floor it is going to start building on layer 69.

Actual results

The slicer is trying to print a circle over open air. Obviously, this fails. I could add supports but I'd never be able to get them out.

Expected results

I had thought it would bridge, then build up layers on top.

@Snargola Just untick Extra perimeters on overhangs:

@discip I thought you were going to say use sacrificial bridges so was surprised to see disable extra perimiters on overhangs. Why does that help?

[discip]

I think it should work better, because it doesn't start printing in mid air.
