So, this is an interesting issue I've begun encountering while working on some very small airfoils recently. Numerous layers seem to, at random points, appear as top/bottom surfaces instead of the intended walls. I can not fathom what exactly is going on here. Attached is a screenshot showing some of the problem, but it is beginning to cause serious complications due to unnecessary stops and starts. Any suggestions?
edit: Added project file. The settings are a mangled husk of the original profile; I threw everything (up to and including the kitchen sink) at this to try and sort it out.
