Infill bug

[Xtrudinary]

Just bought S3D and started to build tweaked profile with simple single layer test shapes. All overlaps set to 0%, extrusion multipliers at 1.0, basically a pure vanilla profile I tune first before the fudge factors are applied. I've used Cura and Slic3r PE but never seen a slicer do what S3D does. There is some strange bug affecting infill calculations on the Y-Axis. Revealing itself in several ways.

The story goes I was targeting a 0.45 extrusion width on a 0.40mm nozzle, 0.2mm layer height. Test object is as simple as it gets rectangle, sized as a multiple of 0.45mm,ie 9x18x0.2mm. Infill is rectilinear %100, angle is 0degree, no perimeter. Basically a line test for Z offset adjusting. All the following bugs show in preview and in the generated gcode.

BUG Example #1
Its only 17 lines, 17 * 0.45mm =7.65mm. This should be 20 lines for 9mm ( 9 / 0.45)

Rotate the object 90degrees, same problem.

BUG Example #2
Adding a 2 line perimeter. Infill still missing lines.

Duplicate the object on the Y-Axis and the incomplete infill shifts.

Here are the factory files I tried to attach to original post.
