Hello, I don't think the feature works, because I tried printing with the settings above (different infill layer thickness) and I had prints on empty layers below (just like the image I uploaded above). I tired increasing the infill percentage from 100% to 110% then 150% and down to 90% and the print time were similar with no change. This informs my decision that there could be an issue somewhere.
Note: This is only applicable for concentric infill as "lines infill" had no issues with this settings.
I did a quick check on previous version 4.13.1 and there were no issues.
Could you please help me on this.
