Description of the bug

I have a model that slices fine with Lightning infill when I do not have a modifier on part of the model to increase the number of perimeters on a very small part of the model. Additionally, if I add the modifier, and change from Lightning infill to support cubic, the model also slices fine. Increasing the overall number of perimeters and using Lightning, also works, although inefficient.

Project file & How to reproduce

There are 2 copies of my model on the build plate, one hidden one not. The copy with the problem has a Generic-Cylinder modifier to set the perimeters of the "spike" to 3. The rest of the model is 2 perimeters. you'll also note that the paint-on supports in this copy do not generate during slicing.

The other copy is just to show that it slices fine with lightning and 3 perimeters overall. The paint-on supports also work properly.

Hide one/show model or the other to see the difference. To get the first model to slice, change to support cubic infill, or delete the "Generic-Cylinder" modifier.

In the zip file, I've also included the project's original models (3MF files, not STLs), including an "old version" that did not exhibit this issue.
