I've been noticing for a while now sometimes I still see broken normals on shapes, while most of these issues have been fixed over the years, one thing is still definately broken here, any corrective shape that triggers with 3 or more other shapes (A+B+C) will distort the vertex normals of the corrected area. It doesnt seem to matter how complex or simple the shape is, the exporter just doesn't seem to calculate it right with 3 or more. I can stack as many A+B correctives on top of each other as I want but a shape with more than 2 always seems to break.

I assume theres no need for a pic as by now you're probably quite aware of what this issue looks like when it happens
